一般注記The "rarefied gas numerical wind tunnel" (RGNWT) for the simulation of rarefied gas flows around three-dimensional space vehicles is under construction. The RGNWT consists of the universal code described using the null-collision (NC) direct-simulation Monte Carlo method and the software for the grid generation and graphic display. In order to ascertain the feasibility of the RGNWT, quantitative comparisons between the NC and time-counter (TC) direct-simulation Monte Carlo methods are made for the shock wave structure and leading-edge flow. It is shown in the leading-edge flow that the NC method is stronger to the small number of simulation molecules than the TC method; the lower limit of the number of simulation molecules for the NC method is less than one third of that for the TC method. The computation time for the NC method is comparable to that for the TC method for the same number of simulation molecules.
