Description

This paper describes a numerical study of a information preservation (IP) method for low-Mach number, microscale gas flows. Reliability of the method is examined for the flows about a micro circular cylinder at the Mach number range from 0.01 to 0.1-and the Knudsen number range from 0.01 to 1.0.. The IP method gives reasonable results at a moderate number of sample size with which the, conventional direct simulation Monte Carlo (DSMC) method gives no meaningful results.
