Flow-Field Numerical Simulation of Gas-Solid Cyclone Separator Based on FLUENT

摘要

In this paper, gas-solid flow-field, pressure changes, velocity changes and vortex properties inside gas-solid cyclone separator are studied under various conditions with software of Fluent. The research results show that velocity along Y axis direction (tangential velocity) and along Z axis (axial velocity) are dominant factors in cyclone, static pressure, velocities in all directions, and separation rate of solid particles in cyclone all increase with increase of gas treating amount, the static pressure in center of cyclone separator is the lowest and solid particles are concentrated on the inner wall of middle section, gas-flowȁ9;s velocities in all directions reduces as particles density increases. However, wear of the cyclone separator wall would aggravate at high particle density. It can be inferred that the characteristics of a cyclone separator with v=18m/s and dust content value being 1% are supposed to be mostly close to calculation result of the empirical model.
