Tangential Velocity in Cyclone Separator

Dehumifying · June 25, 2021, 04:40

Hello everyone, I have tried to simulate a cyclone separator with ANSYS Fluent. In setting solution in Workbench I have followed the steps and instructions according to the validation journal. However, my simulation tangential velocity contour results are different from the validation journal. In the validation journal the tangential velocity contour on the center of cyclone should be low but in my simulation contour it is high. However, the contours of the pressure drop and the axial velocity are appropriate.

Note : I used reynold stress turbulence model (RSTM) and Discrete Phase Model (DPM) to injection modeling

Can you help me solve this problem?

do U define gravity ??? Maybe check this first

Thank you Mr Martin. Yes, i am already define gravity in y axis. But this contour still don't change.
