HI

I want to analyse a cyclone consisting of air+sand . I want to achieve 4 way coupling.
1.I have used DDPM and granular flow model since the volume fraction is greater than 10%.CAN WE USE THIs APPROACH FOR 4 WAY COUPLING?

2.In my case I have an outlet at the bottom and top,I want to literally know how many particles are trapped at the bottom and in the cyclone ,How many are escaped from the top outlet ,so that I can calculate my collection efficiency.

pls give me some insights in order to perform this analysis

WOULD BE GRATEFUL IF ANY KIND OF HELP IS OFFERED
