Investigation of feed flow effect using CFD-DSMC method in a gas centrifuge

In this study, the effect of rarefied region in rotor centrifuge was investigated. a centrifuge, feed inlet is positioned area. The continuum hypothesis not valid area; therefore, it desires to be analyzed by probabilistic methods like Direct Simulation Monte Carlo (DSMC). present Computational Fluid Dynamic (CFD) method used simulate area, and DSMC employed An implicit coupled density-based scheme performed for CFD method, Variable Hard Sphere (VHS) diffuse model were method. Also, local Knudsen number defined determine interface location between continuum-rarefied regions (r=0.086 m). comparison results pure CFD-DSMC illustrated large differences flow properties regions. showed that value separation power obtained from solution 10.5% different.
