Numerical Simulations of Cluster Formation Using a Discrete Velocity Kinetic Theory of Gases.

Abstract

Cluster formation is simulated numerically with discrete velocity Boltzmann model in two space dimensions. The model exhibits cluster coagulation, fragmentation, and transport. It evolves on two different scales obtained from an elastic and inelastic collision Knudsen numbers respectively. For flow impinging on a wall with specularly reflective boundary condition these scales appear both analytically and numerically.
