Cyclone Separator Simulation with ANSYS Fluent Discrete Phase Model (DPM)

May 11, 2023October 9, 2023 mechalab761691 1 Comment

Steady-state CFD simulation of cyclone separator is performed using ANSYS Fluent. Particles are tracked using DPM. One-way coupling is considered without drag. Meaning fluid phase will influence particulate phase via drag and turbulence whereas particulate phase has no influence on the gas phase.
