Abstract
A new class of schemes of the DSMC type for computing near-continuum flows has been recently suggested: the time-relaxed Monte Carlo (TRMC) methods. An important step preceding the wide use of these schemes is their validation by classical homogeneous and one-dimensional problems of gas dynamics. For this purpose, a plane Couette flow is considered in the present paper. A comparison of TRMC results with the data obtained by time-proved schemes of the DSMC method (here we used the Majorant Frequency Scheme) in a wide range of Knudsen numbers and for different values of wall velocity is presentedFile in questo prodotto:
