DIGITAL PHYSICS SIMULATION OF LID-DRIVEN CAVITY FLOW

Digital Physics is a new extension of the lattice-gas concept for the simulation of fluid how which removes disadvantages that prevented pra ctical application of the original method. The extensions are summariz ed. 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 num bers and geometries are compared with experiment, CFD and the lattice- Boltzmann BGK method. Accurate results are obtained with the new metho d.
