Gas-kinetic schemes developed from the BGK model have been successfully applied to 1D and 2D flows. In this paper, a novel 3D method for the system of conservation laws of fluid flow is constructed. A Lax-Wendroff type scheme is developed from gas-kinetics and applied to solve time dependent problems. In the limit of infinite collision time, the formulation reduces precisely to the kinetic representation of flux vector splitting for the Euler equations. A new time-independent flux formulation is further introduced, which when applied in conjunction with Jameson's multigrid time stepping scheme yields efficient and accurate solutions of steady compressible flows.
