Research on Simulating Structural Parameters' Impact on the Flow of Two Phases in Separator

Abstract

Adopting the RSM (Reynolds stress model) to conduct numerical simulation on gas phase flow field in bypass cyclone separators with two kinds of inlet structure, meanwhile, interphase coupling discrete model DPM is used to simulate the trace of particles in bypass cyclone separator. At last, the results demonstrate that the separating efficiency of separator B with a large length-width ratio inlet increased 1%~2% and the pressure drop is smaller when compared with separator A. A low average entering position and a short distance to the wall are helpful to improve the separating efficiency.
