In this writing we'll try to find causes of this effect. To do that, we'll look into two computed numerical models of open clusters, wich shows similiar diversion. On simple observations and statistical analysis we'll design methods to accurately calcula te velocity dispersion and afterwards we'll verify correctness of these methods. Then we'll use these methods to investigate evolution of velocity dispersion in both used models of open clusters.
