ABSTRACT
The organization of this paper is as follows. In the next section, we briefly introduce the setup of our numerical experiment. In section 3, we summarize the result of our simulation for granular gases for Haff’s law (Haff 1983), VDF and the cluster formation in the freely cooling state. In section 4, we discuss our results and plan for the actual experiment in both the usual environment and the microgravity environment. In the final section, we conclude our results.
