Abstract

Direct Simulation Monte Carlo (DSMC) is a widely used statistical numerical simulation method based on molecular motion. But in terms of the DSMC method. When we are simulating the gas flow at low speed, he molecular thermal motion speed is bigger than the macroscopic movement speed. If we want to get meaningful statistics, we need a great deal of sampling number. So the DSMC method is not suitable for simulation of gas flow at low speed. Jing Fan and Qing Shen come up with Information Preservation (IP) method. In this paper, on the basis of theoretical analysis, we improved Matlab codes for the DSMC calculation of Couette flow. We compared DSMC method with IP method in numerical simulation of micro scale one-component gas flow at low speed to validate feasibility and accuracy of IP in gas flaw at low speed.
