Abstract:

A convergent theory for the density dependence of transport coefficients for a moderately dense gas is discussed. Since the terms in the original density expansion depend upon the dynamics of successively higher numbers of particles, one can classify the divergences that appear in terms of the associated dynamical events. The most divergent terms are always determined by sequences of binary collisions. The summation of the most divergent terms produces a collision damping which keep the interval between successive binary collisions to within a few mean free times. The resummed expression for the viscosity due to Kawasaki and Oppenheim was partially evaluated. One can say that terms proportional to n to the d-1 power log n, where d is the number of dimensions, appear in the density expansion, however, the precise coefficients of the logarithm have not yet been established.
