Collision Integrals of a Gas of Rigid Convex Molecules

Abstract

A review of the collision dynamics of rigid, smooth, and convex molecules with zero, two, or three collisionally active rotational degrees of freedom is given, together with a review of the kinetic theory of a general gas mixture of such molecules. A method for performing the momentumlike integrations of the collision integrals for gases of this type is discussed, and general formulas for the evaluated integrals are presented. Some properties of the linearized Boltzmann equation are demonstrated on the basis of these results.
