Computational Fluid Dynamics (CFD) describes the process of computer-assisted solving of fluid mechanics and thermodynamic equations (i.e. Navier-Stokes equations). This method is a highly efficient and time-saving alternative to traditional experiments on a test rig. On the one hand, running this method requires profound knowledge in numerical and applied mathematics, and on the other hand, it also requires broad technical expertise with fluid mechanics and thermodynamics. Since this particular method includes modelling assumptions regarding the phenomenon of flow turbulence, and this phenomenon occurs in most industrial flow processes, the knowledge mentioned above, and a high level of experience is needed in order to generate high quality CFD results. For all these reasons, CFD is more than the well-known “colorful” depictions often found elsewhere. DrS3 purposely refrains from using these representations on the webpage since these colourful images explain very little to those who are unfamiliar with the complexity of CFD simulations.

As a member of the European Research Community on Flow, Turbulence and Combustion (ERCOFTAC), DrS3 takes advantage of the dense network of universities and companies conducting state-of-the-art CFD research and the highly relevant results produced within the network.

Previous customer CFD projects of DrS3 include the following areas and research:

  • Calculation of heat transfer coefficients in counter-flow heat exchangers
  • Wind load calculation for buildings and industrial installations
  • Calculation and optimization of hall ventilation
  • Analysis of film flows
  • Calculation and optimization of small hydro power plants

For running CFD Simulations, DrS3 is using the following state-of-the-art software products:

  • ANSYS CFX, ICEM, ANSYS DesignModeler, OpenFOAM
