cyclone simulation
 

Hi all

please help me with cyclone simulation. I would like to simulate flow with dust particles, steady flow, pressure difference should be between 1100kPa and 600kPa. Also I cannot see any good result of plot, residuals are so bad. I have 1 injector, and use Lagrangian multiphase

any help approciated

Cyclones are hard.

What turbulence model are you using? You should start with standard linear ke and switch to quadratic, then switch to RSM. If you particles are smaller you may want to consider using EMP instead.

What is your grid? If you can generate a structured grid, do it.

Use polyhedral mesh. the convergence will be good.

Hi
Thank you. Seems it's working
