Abstract

Digital Physics is a new extension of the lattice-gas concept for the simulation of fluid flow which removes disadvantages that prevented practical application of the original method. The extensions are summarized. Simulation results for a three-speed model demonstrate the absence of artifacts and significant reduction in viscosity. Also, simulation results for 2D and 3D lid-driven cavities for a range of Reynolds numbers and geometries are compared with experiment, CFD and the lattice-Boltzmann BGK method. Accurate results are obtained with the new method.
