BFH expands competencies in Computational Fluid Dynamics

23.08.2023 Wherever fluid flows, heat, and acoustics are concerned, the Computational Fluid Dynamics CFD method has proven its value in recent years. In order to support business partners more efficiently and to include this method in the research, the BFH has strengthened its expertise in this field.

The Computational Fluid Dynamics CFD method refers to a numerical flow simulation. In this process, flows (e.g. of air, liquids, or heat) and flow patterns are simulated computationally. The simulation helps to better understand flow behavior under various circumstances. This understanding can be used to optimise systems.

The method can be applied in many areas, from agriculture to health care. At the Bern University of Applied Sciences, we focus on the influences in the construction sector.

The main advantages of the method include:

  • Significant reduction in the number of tests/lab experiments 
  • Detailed analysis of occurring physical phenomena
  • Considerable time and cost reduction in the design and development phase of products
  • Parameter study to optimise the geometry and finalise the most advantageous model
  • Possibility to compare different results based on various input parameters
  • Comprehensive analysis to select the desired scenario for prototyping

The method has already been used in various research projects: analyses were conducted in building physics, fire spread, and material properties for a new type of wall structure in timber construction. In a second project, a heating, ventilation, and air conditioning system in a window frame was optimised. The air exchange rates, thermal retention, and moisture distribution were analysed using CFD.

In addition, the new section intends to make an active contribution to the university by offering courses for Bachelor's and Master's students, conducting workshops, and supporting students in their semester and final theses.
