Abstract
Cluster expansions are presented for the collision bracket integrals for transport cofficients of a dense simple fluid which appear in the kinetic theory of dense fluid reported previously. The density series calculated with the cluster expansions are given in exponential forms and their leading terms consist of a connected three-particle collision operator. The three-particle contributions are discussed in terms of mass-normalized coordinates which make it possible to put them in forms structurally rather similar to the two-particle collision bracket integrals in the Chapman-Enskog theory. The three particle contributions are thus cast into forms suitable for numerical computation.
