Abstract:

A model of a cyclone separator is built by using Gambit, and the mesh model of the cyclone separator is generated. By numerical simulation of flow field of cyclone separator are internal gas and gassolid twophase flow simulation, after observing the results of numerical simulation can be found in gas velocity into the cyclone after the first increases and then decreases, then around the external cyclone downward movement after the movement to the bottom of the cyclone separator began to move upward along the same direction. In addition, the smaller diameter particles in the cyclone separator have larger turbulence than the larger diameter particles, and the degree of chaotic motion is greater, and the difficulty of separation is also increasing.

Key words:

cyclone separator, numerical simulation, gassolid twophase flow, separation efficiency
