Abstract

A commercial software fluent 6.1.22 of CFD has been used to model a single inlet and a double inlet cyclone. Lagrangian model is employed to solve the particle momentum. It illustrates that particles with different inlet positions have different separation efficiency. And furthermore, a comparison has been involved to a single inlet and a double inlet cyclone, and it shows the separation efficiency of the double inlet cyclone is 5-15% greater than that of the single inlet cyclone with the same inlet size and vortex finder diameter. The result is similar to K. S. Lim, S. B. Kwon and K. W. Lee's test data.
