| Abstract: | Direct simulation Monte Carlo method is a technique with which a rarefied gas flow is simulated by using computing model of thousands of testing molecules.DSMC method is written to solve the couette flow between two parallel plates.Models for intermolecular collisions are assumed to be hardsphere models.The results show that there exist velocity slip and temperature dump near the boundary. |
