Investigation gas behavior inside a gas centrifuge using dsmc code developed and dsmcFOAM solver

Abstract

To model a gas behavior within a centrifuge machine, a powerful tool is required similarly. With high-speed cover, all the computational limitations for applying the influential derives such as feed, scoop, baffle effects, etc., formed flow regimes. Therefore, achieving an applicable code or software to simulate the gas behavior within a centrifuge machine to investigate the effect of the derives on the separation in a centrifuge machine, including high-speed rotation, temperature, and mechanical derives, is required. Considering the fact of covering the method based on the molecular DSMC for the all formed flow regimes within the centrifuge machine, in the present work, the method of applying the all influential factors in a separation process of a centrifuge machine in the axial symmetric coordinates on the written code of DSMC and also the dsmcFOAM solver have been studies. The results have been compared with those obtained from the code, including pressure radial changes, axial mass flux, velocity components, and dsmcFOAM solver. A good agreement was found between the results corresponding to the written code and dsmcFOAM solver to simulate a centrifuge machine in the presence of all the parameters.
