Rarefied Gas Flow Modeling inside Rotating Circular Cylinder
- 1 Urmia University, Iran
Abstract
In this study a rarefied gas flow inside a rotating circular cylinder by means of direct simulation Monte Carlo (DSMC) method is investigated. A rarefied gas is supposed to be contained in a cylindrical domain, bonded by a rotational cylinder with smooth and diffuse-reflection surface. The top and bottom ends of domain is assumed to be speculary-reflecting. Special attention is focused on the effect of parameter L/D, where L and D are the cylinder length and diameter, respectively. The investigation on the formation of various kinds of flow patterns in the range of various values of the L/D are important aims of the present work. Finally computed results such as density fields and velocity profiles are shown and discussed.
