Fluid Flow & Heat Transfer
The application of Computational Fluid Dynamics (CFD) software is a modern and powerful investigation method of complex realistic flows in order to achieve the understanding of flow phenomena. Therefore, such modern tools are today a reliable basis for optimization of configurations with respect to the flow path and associated pressure losses, aerothermal mixing of fluids and combined flow and heat transfer. B&B-AGEMA uses such modern software and tools and offers services on following topics:
- 3-D flow analysis in the fields of power technology, especially in oil & gas technology
- 3-D flow analysis of vehicles including ventilation
- 3-D flow analysis in the surrounding area of buildings
- combustion simulation
- two-phase flow simulation, gas mixtures
- flow in exhaust gas channels
- simulation of free surfaces
- condensation and evaporation
- flow in cooling channels
