gas-solid flow in cyclone
 

For the standardk-¦Åmodel each quantity ¦Õ the corresponding conservation equation of momentum or turbulence can be summarized in general form.

where ¦Õ can be ¦Å,k,u,the source term of gas and particle phase and so on. The source term can be defined when considering the interaction of particle-gas and particle-particle. However, I am not certain of whether I consider this in Discrete Particle Model when using Fluent 6.1 or not. On the other hand, if I use the Reynolds Stress Model to simulate the gas flow of cyclone, whether I can change the source term like the above? Your suggestions will be grateful for me. Thanks!
