On the time relaxed Monte Carlo computations for the flow over a flat nano-plate

摘要: Abstract In the present study, first, second and third orders of TRMC scheme (TRMC1, TRMC2 TRMC3 schemes) are employed to numerically investigate Argon flow over a flat nano-plate with different free stream velocities variety Knudsen numbers. The simulations cover regimes from early slip transition (0.00129 ≤ Kn ≤ 0.09). Higher order terms in Wild sum expansion considered obtain higher collisions. results compared those standard DSMC method. Comparisons show that among studied schemes, obtained have excellent agreement ones On other hand, TRMC1 schemes deviations more pronounced for temperature pressure distributions. Moreover, investigation illustrates as number increases accuracy lower improves. It is observed truncating up approximation scheme, may be proper alternative method simulating numbers 0.00129 ≤ Kn ≤ 0.09 reasonable simplicity mathematics.
