Tips & Tricks: How to interpret results for multiphase & porous domains using true velocity and superficial velocity

A commonly asked question is: What is Superficial Velocity and when do I use it?   If a fluid flows through a region that is occupied by either fixed structures (a porous region, pipe rack, catalyst bed, etc...),¬†or shares the channel with other fluids (e.g. gas-liquid flow), there are two ways to describe the fluid...
