Triple Collision Effects in the Thermal Conductivity and Viscosity of Moderately Dense Gases. Part 2
Abstract
Calculations of transport properties of dilute gases are always based on the Boltzmann equation. The Boltzmann equation accounts only for the effects of collisions between two gas molecules. To predict transport properties of moderately dense gases one needs to determine the effects of collisions among more than two gas molecules. The report studies the contributions to the transport properties caused by collisions among three gas molecules. It is demonstrated that the first density correction to the transport properties can be represented by a series of collision integrals associated with one, two, three and four collisions between three gas molecules. Numerical studies for calculating the dominant collision integrals are made for a gas of hard spherical molecules.
