Schiller-Naumann Model for Sparsely Distributed Flow
 

Dear All,

I am new to the CFX, However I am reading the CFX guide for the multiphase flow. In that there are models for the Drag phenomena. I was able to find the limits of application for the Gidaspow and Wan YU model, which is based on the volume fraction of the continuous phase. However I could not find the range of application for the Schiller-Naumann Model. I would also like to know what is the criteria for the Sparsely and Densely distributed particles, I mean the range of the volume fractions?

If somebody will help me then I would be very much grateful
