Rarefied Couette flow between concentric rotating cylinders is investigated using Maxwell’s slip-velocity boundary treatment. The study provides an independent reassessment of the velocity inversion process and demonstrates that the occurrence of an inverted velocity profile depends solely on the accommodation coefficient of the stationary outer cylinder. From the analysis, criteria are derived for the accommodation coefficient of the outer cylinder that can be used to predict whether an inverted, partially-inverted or normal velocity profile will occur. The present results are in close agreement with previous analytical solutions and in good qualitative agreement with available DSMC data. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR] |
