Our speciality: Fluid mechanics


Fluid mechanics - ever heard of it?
Our landing page image shows a Kármán vortex streetafter the Hungarian-American physicist von Kármán, 1881-1963. This phenomenon can be observed in fluid mechanics when, for example, a plate is flowed around with a Reynolds numberdimensionless characteristic of the degree of turbulence, after the British physicist Reynolds, 1842-1912 around 100. Here, alternating vortices are created, which lead to pressure fluctuations. These can be so strong that (without appropriate countermeasures) they can cause a bridge to collapse. This is what happened to the Tacoma Bridge in 1940. Your favorite search engine will yield interesting videos.

Fluid mechanicsalso fluid dynamics are part of physics and deal with the laws of all flowing substances, i.e. liquids and gases. The air that surrounds us, the water of the oceans, the blood in our bodies. All of this is unthinkable without fluid mechanics. From these examples it is clear that bodies can be flowed around (e.g. in aerodynamics) or through (e.g. in pipes).

Turbomachinery forms a subfield of fluid mechanics. Within these hydraulic powerPhydr = volumeflow ∙ pressure difference is converted into mechanical powerPmech = torque ∙ angular speed and vice versa. Energy can be added to fluids (e.g. to pump water through a hose), by means of pumps, fans or compressors. The above picture shows the compressor side of a turbocharger, here, as can be assumed, (intake) air is compressed. On the other hand gas, water or wind turbines are used to extract energy from the fluid (e.g. to generate electricity by means of generators within power plants). The quality of the energy conversion is defined as efficiencyη(greek: eta) = Phydr / Pmech (e.g. for pumps). This value is usually given in % and the higher it is, less losses occur in the machine.

You will find fluid mechanics and turbomachinery in all areas of daily life. This can be seen from some examples below. Depending on how many aspects you look at, these scopes merge into each other, since machines / devices usually consist of several assemblies / parts:

Energy technology

  • Separator / filter unit
  • Gas / steam / water turbine
  • Heater / heat exchanger
  • Wind power plant

Household appliances

  • Cooker / cooker bonnet
  • Refrigerator / deep fryer
  • Hoover / hairdryer
  • Washing machine / dryer


  • Car / train / air plane
  • Computer / electronics
  • Underground car park
  • Building / Tunnel

Transport / Supply

  • Lift / elevator
  • Gas / water meter
  • Pipeline / valve
  • Pump / fan

As you can see, you come into contact with fluid mechanics on a daily basis. And now you know at the latest that „flow“ mechanics does not deal with (flowing) electricity… In any case not directly.

Our field of application in general


The field of application of our engineering office is not limited to fluid mechanics, but also includes peripheral disciplines such as structural mechanicse.g. FEM topology optimization (see adjacent animation), thermodynamics and electromagnetics. Calculations or simulations enable us to develop or optimize efficient and sustainable products. In addition, simulations significantly reduce development time and the number of prototypes. We would like to emphasize that a simulation is only a tool to validate the design or to optimize details. The creative solution finding is based on the ingeniousness and competence of the person sitting in front of the computer. With our many years of experience, we also support you in procuring and testing prototypes. In summary: Our focus is on the pre-development / optimization of innovative products using state-of-the-art simulation methods, from the concept phase to pilot production.
