  A recently introduced particle-based model for fluid flow, called Stochastic
Rotation Dynamics, can be made Galilean invariant by introducing a random shift
of the computational grid before collisions. In this paper, it is shown how the
Green-Kubo relations derived previously can be resummed to obtain exact
expressions for the collisional contributions to the transport coefficients. It
is also shown that the collisional contribution to the microscopic stress
tensor is not symmetric, and that this leads to an additional viscosity. The
resulting identification of the transport coefficients for the hydrodynamic
modes is discussed in detail, and it is shown that this does not impose
restrictions on the applicability of the model. The collisional contribution to
the thermal conductivity, which becomes important for small mean free path and
small average particle number per cell, is also derived.
