    Flow Simulation: Defining porour media

    Isaac Johnson

      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).

          Isaac,

           

          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.

           

          I hope this helps
