Numerical Simulation of the Gas Phase of Cyclone-Separator Sand Trap Based on ICEM CFD and FLUENT

Article Preview

Abstract:

This paper is based on Reynolds stress model and uses a very important tool called ICEM CFD,which is integrated in ANSYS Workbench to mesh the cyclone-separator sand trap. From the Hexahedral structured meshing and analysis of its internal gas movement of the cyclone-type sand trap, the results are shown that mesh quality meets the requirements of solver by using the advanced O-grid and Y meshing technology in the software of ICEM CFD. Moreover, the existence of the short-circuit flow and the secondary flow is proved in the analysis of speed of the gas phase in the cyclone-type sand trap. From the information above, optimize designers can chance the structure of the cyclone-type sand trap in order to improve the separation efficiency of the cyclone sand trap and then to provide more valuable parameters for assessing and analyzing the impact of stubble height and surface crop coverage on wind erosion.
