ABOUT US

Competent partner for your engineering demands. 

In the competition for the best products the solution of multi-physics problems plays an increasingly important role. SES-Tec, stands for Scientific & Engineering Simulation – Technology and supports customers in the field of multi-physics simulations and the creation of simulation methods. SES-Tec was founded by Dr. Wolfgang Lang and Dr. Dalibor Jajcevic in 2013.

The core competencies of SES-Tec comprise the creation and application of numerical methods of fluid dynamics, thermodynamics, structural mechanics and particle and process engineering. To get the maximum out of the available opportunities for the customer, SES-Tec see themselves not as pure development service provider, but more as a development partner.

Therefore, they also offer a holistic approach of development, which extends over the definition of the boundary conditions and selecting the simulation environment and completes with integrating the solution into the products of the customer. The portfolio of SES-Tec consists of three areas, simulation tools development (development of customized models and expansion of implementation of customer-specific models in commercial programs), consulting & services (for various sectors such as the automotive sector, aerospace, general engineering, pharmaceutical and chemical industries) and training.

SES-Tec wants to show that numerical modelling and elaborate “high-end simulations” can be efficiently used in the product development process in companies of all sizes, through the use of appropriate simulation tools and a largely automated workflow. This should be done by using appropriate software and highly efficient workflows, which are adapted to the needs of the individual customer.

AVIATION

AVIATION

Aviation has pioneered the use of numerical methods in the design of transonic wings for commercial aircrafts, so it is not surprising that simulations are established in this area like this. For example, the period for developing a new aircraft extends over about 10-15 years. The aerodynamics regarding security play a decisive role. You can simulate both the individual components as well the overall model. The numerical aerodynamics offer the following advantages

  • Reduction of development times
  • Compliance with the laws of similarity
  • Parameter variation is easily possible
  • the entire flow field is available

However, statements can be made on the ventilation of the climate in the passenger compartment of an airplane, whereby a contribution to the well-being of passengers during the flight can be made.

We are looking forward to consult you in detail and to inform you about further possibilities of simulations.

In the field of aviation we are offering the following applications

  • aerodynamic

  • Icing of airfoils
BUILDING AND HOUSING TECHNOLOGY

BUILDING AND HOUSING TECHNOLOGY

Also in the field of building construction, simulations can generate an added value for our customers in the planning phase. There are usually issues such as energy efficiency of air conditioning or fresh air supply for an office building. Even parameters such as indoor environment can be examined at an early stage. In the field of building and housing technology, also safety issues can be relevant such as the spread of smoke in public buildings (for example in a car park or a shopping center, etc.) We are looking forward to consult you in detail and to inform you about further possibilities of simulations.

We are offering diverse applications in the field of building and housing technology, as for instance

  • 3D tunnel simulation
  • smoke propagation
  • aerodynamic
  • cooling technology

PHARMA INDUSTRY AND BIOTECHNOLOGY

PHARMA INDUSTRY AND BIOTECHNOLOGY

Production of pharmaceuticals is often performed in multiphase flow systems, such as gas-liquid-solid, gas-solid, liquid-liquid or gas-liquid. Computational Fluid Dynamics and other methods such as the Discrete Element Method are the common methods to predict this phenomena.

These types of simulation are extremely complex and require often a multiphysics calculation, which can be coupled with several computational codes. SES-Tec provides support in the selection of a suitable computational platform and software. Furthermore we extend and develop coupling methods and validate obtained simulation results.

We are looking forward to consult you in detail and to inform you about further possibilities of simulations.

In the pharma industry and biotechnology we are offering among other things the following applications

GENERAL MECHANICAL ENGINEERING

GENERAL MECHANICAL ENGINEERING

Devices in general engineering are often produced in large quantities, thus it is important to optimize the manufacturing costs and the function of the elements as good as possible. Nowadays computational fluid dynamics is an integral part In the process of product development, which extends over the first idea through to the series production.

We are looking forward to consult you in detail and to inform you about further possibilities of simulations.

PLANT ENGINEERING

PLANT ENGINEERING

If one uses simulations already in the engineering phase, a reduction of many risks already in the virtual system or in the virtual process is possible. The plant engineering appears predestined for the virtual development. This is because prototypes are here relatively expensive and solutions and systems are almost always exclusively customized ones. We support our customers in the selection of the necessary process parameters or in the review of the technical feasibility of various processes and systems.

We are looking forward to consult you in detail and to inform you about further possibilities of simulations.

In the field of plant engineering we are offering the following applications

AUTOMOTIVE INDUSTRY

AUTOMOTIVE INDUSTRY

In the automotive sector aerodynamic studies contribute a substantial portion to comfort, safety and efficiency. Almost all components of a vehicle, which are in contact with air, water, fuel, exhaust, coolant, lubricating oil or hydraulic fluids can be detected in a flow simulation. Through CFD simulations it is possible to analyze and optimize the design of the vehicle or individual components. Inside a vehicle, it is possible to analyse the cold and hot air flow by flow calculations to create comfort for passengers and at the same time to ensure the ventilation of the windscreen makes a clear view. Furthermore by simulating the engine compartment flow there is the possibility to optimize the fuel and thus simultaneously reduce costs.

The use of computational fluid dynamics (CFD) in the automotive sector is an ideal complement to conventional trials and tests. Simulations are a fast and efficient tool to drive development forward, among others, in the automotive industry.

We are looking forward to consult you in detail and to inform you about further possibilities of simulations.

In the field of autmotive we are offering the following applications

  • IC-engine simulation
  • acoustic
  • aerodynamic
  • cooling technology
  • waste heat recovery
  • valve simulation
SELECTED APPlCATION FIELDS

SELECTED APPlCATION FIELDS

Hereinafter a few selected application fields are described in more detail.

  • VALVE SIMULATION
    In some cases, such as reed valve simulation of a two-stroke engine, fluid-structure interaction plays an important roll and should not be neglected. The simulation is part of multiphysical simulations and can be highly complex and time consuming. The high-end simulation requires huge level of knowledge and experience, especially for the industrial application. SES-Tec has developed a work-flow, which helps non-experienced users to realize the complex simulation with a high level of accuracy and concurrently to ensure this in a realistically computing time.
  • BIOREACTOR
    Bioreactors are used for bio-pharmaceutics production typically plant, bacteria, fungi, algae or animal cells. From the simulation point of view, the bio reactors are mixing devices, which can be successfully analyzed applying Computation Fluid Dynamics (CFD).

    The focus of SES-Tec simulation methodology is to obtain the bio-reactor’s process parameters, such as mixing time, volumetric oxygen mass transfer coefficient, shear rate, dissipation energy, power and input numbers, etc., from CFD-simulation. These parameters can be evaluated for different types of bio reactors and therewith indirect their influence on the cell growing process itself. Furthermore, scale-up and –down of a bioreactor can be analyzed using CFD computational technology without a need to build-up a prototype.
  • ACOUSTIC
    Our welfare in the daily life is hardly affected by the sounds of our environment. Especially in areas, which have bad acoustic properties, sounds are growing louder due to their reflection. Due to that reducing noise can help to decrease noise-induced stress. Furthermore, a respective design of, i.e., the interior acoustics of a car, is an important contribution to driving safety. There are lots of different fields, where acoustic simulations are done by us, such as automotive (mufflers, air filters,…), construction (ventilation systems, silencer, air conditioning,…) and general engineering (i.e. compressors, piping systems, vacuum cleaners,…).
  • 3D TUNNEL SIMULATION
    Construction-related works are usually very expensive projects, especially in the field of building tunnels or other huge public projects. In term of costs, an extremely detailed planning phase is necessary to keep them to a minimum. This requires various simulations to enable to avoid all possible malfunctions. SES-Tec provides support in the planning phase of huge building projects and helps to keep costs to a minimum by answering questions such as how big the momentum forces on vehicles are, how the temperature distribution in tunnels is and what gas forces are acting and many more.
  • AERODYNAMIC
    Aerodynamic is much more than just car or truck design. Characteristics, such as driving performance, comfort, cooling, applied forces, vehicle dynamics etc. are important factors, which have to be taken into account during the development process of a vehicle.

    SES-Tec offers an extremely efficient simulation work flow, which enables to support you already in the vehicle design phase on fundamental and strategic decisions in order to achieve the most efficient aerodynamically characteristics with simultaneous reduction of development costs.
  • COOLING TECHNOLOGY
    We are offering our customers expertise in the cooling technology, such as thermodynamic assessments of cooling system layouts (i.e. fridge, freezer, wine cooler,…), modelling of various cooling cycle layouts, simulation model development (i.e. for heat exchanger, capillary tube, compressor, fan, etc.), 3D-simulation of various types of heat exchangers and compressors, development of thermophysical models and modeling of freezing processes.
  • SMOKE PROPAGATION
    The causes for injury and death at fire events is due to the exposure of combustion products (smoke and gaseous) rather than to the fire itself. Therefore in modern building design it is essential to provide emergency exits at the right locations.SES-Tec supports the process of finding right locations for emergency exits by using modern simulation tools in the engineering phase of the building. This reduces costs, as there is no need for later modifications on the completed construction and saves lives due to the right location of the exits.
  • WASTE HEAT RECOVERY
    Energy efficiency is of the greatest importance in the development of a new motor. The thermal energy recovery from the waste heat in a Rankine-cycle represents a promising technique for an efficient use of fuel energy. By the reason of the complex system requirements in the automotive sector there is still no functioning system on the market. The choice of a suitable working fluid, which meets these requirements, is therefore of significant influence for the selection and design of the necessary components for the cycle. In addition to working fluids such as water, alcohols or refrigerant, the group of silicone oils also represents an interesting alternative.

    The design of such a system is influenced by the selection of a suitable working fluid and many other parameters. The most important can be summarized as expander, evaporator, capacitor and pump.For a working system it is important to consider all these aspects and all these under highly transient loads, such as those in the automotive sector. SES-Tec offers you know-how and experience in the design and simulation of such systems and supports you in the entire development process.
  • IC-ENGINE
    To understand the highly complex nature of flow in an IC-engine is essential to improve its performance. However, the occurences like reciprocating motion of piston, motion of valves, turbulence generation, spray and mixing lead to a complex flow pattern. Computational Fluid Dynamics (CFD) is a very useful tool to compute and understand this complex flow pattern.
  • FLUIDIZED BED
    A fluidized bed is created when a quantity of a solid particulate substance is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid. This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in the medium then having many properties and characteristics of normal fluids, such as the ability to free-flow under gravity, or to be pumped using fluid type technologies. The resulting phenomenon is called fluidization. Fluidized beds are used for several purposes, such as fluidized bed reactors, fluid catalytic cracking, fluidized bed combustion, heat or mass transfer or interface modification, such as applying a coating onto solid items.
  • COMPRESSION TECHNOLOGY
    A compressor is a fluid energy machine used for compressing gases. Only a few people know that reciprocating compressors are used in many areas in our daily life, such as food industry,  petrochemical industry, compressed air treatment plants, biogas plants as well as in the household.
    In all these areas reciprocating compressors are responsible for a significant share of energy consumption of different technical processes.
    Therefore improving the compressor leads to an increasing efficiency of the entire system. In the field of compressors we offer our clients a holistic approach for developing in the compression technology, from the first rough design of a new compressor to a detailed design of various components such as valve, crankdrive, etc.
