Progress of technology and the ability of construction of devices in micro and nano scales, have developed a new field of science that the classical laws of fluid dynamics can not be analyzed in by the well known Navier-Stokes Model. So, research fields in micro and nano scales have been paid attention more. In micro and nano scales, due to small size of characteristic length, the fluid is rarefied and the behavior of the fluid and its interaction with surfaces and walls in such scales is very different from those in large-scale systems. So, the particle-based-methods like Direct Simulation Monte-Carlo (DSMC) method have been considered one of the most interesting fields of researches for...
