FLOW-3D‘s porous media model is well suited for simulating flow in filters. There are a number of drag formulations which can be applied to determine optimal designs, which will capture particulates well and minimize drag. Particles can be introduced with a range of sizes or mass to determine the trajectory of the particulates.
Data output that can be analyzed includes velocity profiles, residence time, distance traveled by fluid, strain rate, and stream lines. It is also easy to extend the capability to predict clogging and the resulting additional drag through customization. Flow Science offers a number of numerical routines available for modification.
