I run my cyclone simulation in fluent but instead having a swirling flow, my particles just go straight down the cyclone. I used Mixture, RSM, high order discretization model. Could anyone plz tell me wht I've done wrong? is it my boundary condition? Thank you in advance

Are u using "Discrete phase model" (DPM) for the particle tracking..??? Also activate "interaction with continous phase"

for DPM model should I use injections? or i can put my particles in the inlet stream straight away? If i have to create an injection, my particles is not listed in the material list... How can I create one? Thank u in advance
