Drag Force UDF in Non-Newtonian (powerlaw) Fluid

Hello,
I am going to simulate the behaviour of micron-sized particles in an non-Newtonian fluid medium. In fact, the flow viscosity follows the "power-law". I know that "DEFINE_DPM_DRAG(Drag_force,Re,p)" can pass the force per mass of each particle to Fluent, and that the returned valuee must be in form of "". As you know, in powerlaw fluid, Re is defined as and being the particle diameter and the "consistency index". The problem is, how does Fluent define Re number? Does Fluent think of Newtonian Re or this definition of Re? Should I pass this Re in "18*Cd*Re/24" or the Newtonian Re? Thank you! |
