I'm using Solidworks 2012 Flow Simulation in order to model air flow through a pleated paper filter.
Does the geometry of the porous media in my model need to match the geometry I input to define the porous media in the engineering database (length and area)?
For instance: When modeling a filter, do I need to model each individual pleat, or can I use a simple rectangle but change the definition of the porous media in the engineering database (the length and area) to reflected a thin pleated surface? (I have necessary data to define pressure drop as a function of mass flow rate).
We both are struggling with similar FL issue, I think my design is a bit more complicated.
Any ways, for your model, you need to know the porousity value of the filter, then length and area. once you know these parameters. Design it as a solid body and define the porousity values. And the most important is to define the pressure drop Vs mass flow rate curve.
