Numerical simulation of the velocity distribution for a hard-sphere gas

The kinetic features of energy exchange between hard-sphere molecules are numerically simulated. The results deviate from the usual the Maxwell distribution. The high-speed tail of the molecule distribution is cut off due to the dominant deceleration of fast particles. For mixtures of gases with var...

Description
Summary:The kinetic features of energy exchange between hard-sphere molecules are numerically simulated. The results deviate from the usual the Maxwell distribution. The high-speed tail of the molecule distribution is cut off due to the dominant deceleration of fast particles. For mixtures of gases with various molecular masses, the energy redistribution between the degrees of freedom leads to different stationary temperatures of the components.
