Abstract

The quantity of collision rate (CR) is one of the most important parameters that need to be taken into account when dealing with gas dynamics of unsteady regime due to its role in determining the final conditions of the gas-phase formed clusters. In the present work, the so-called direct simulation Monte-Carlo (DSMC) method has been used as a computational tool to investigate the transportation modes of laser-generated Plume (LGP) of Si target into He inert gas. For this purpose, the spatial evolution of the quantity of CR has been temporally traced among the entire space of flow field. The existence of several previously reported phenomena using different physical quantities such as number density, temperature and velocity have been also explored and confirmed. An excellent agreement with our current works has been found. These previously noticed phenomena may include oscillating behavior of vapor front and interaction of shock compressed wave with both of substrate surface and vapor front.
