Abstract:The status quo of theory study on heavy medium cyclones was briefly introduced and commonly used basic equations and numerical computational models of various kinds of turbulent flows in the computational fluid dynamics were also given. What’s more, an exploratory numerical simulation was made to the heavy medium cyclone flow field using such three models ask-ε, RNG and RSM under identical boundary condition. The comparison between this simulation and the experimental measuring results under identical boundary condition indicates that, the RSM model is the turbulent flow model more suitable for use in numerical simulation of heavy medium cyclone field.
Keywords:heavy medium cyclone  turbulent flow model  numerical simulation
