Abstract:

In order to predict the first density corrections to the transport properties of gases, it is necessary to consider collision integrals that account for the effects of collisions among three molecules. For a gas of hard spherical molecules such three-particle collision integrals can be decomposed into collision integrals associated with sequences of one, two, three, and four successive collisions among three molecules. In the present technical report the authors calculate these three-particle collision integrals for the coefficients of thermal conductivity, viscosity, and self-diffusion.
