Main Topic of Discussion

catalytic converter porous media modelling

Complex or small structures can be difficult to mesh and we often need to use a porous media modelling approach to capture the momentum changes (pressure drop).  This approach can help us represent screens, filters, radiator fins, or any other small structure that we don’t want to resolve with a mesh but will influence momentum transport.  Depending on the amount of pressure drop and the actual geometric characteristics of the area of interest, we can leverage different models (cell zones, baffles, or boundary conditions).

  

As part of our “Learn by Example” Webinar series, this session will provide a practical introduction to porous media models in the volume and at boundaries.  We’ll walk through some of the theory and demonstrate how to use these models in HELYX.

Who Should Watch?

CFD Engineers who are performing simulations involving screens, filters, radiators, complex structures that you want to approximate with a porous media approach.
