摘要

The thesis describes the implementation and analysis of a flow algorithm on the DNSP (AT&T's/Delft Navier-Stokes Processor). The flow algorithm is used for the solution of natural convection problems in 2D and 3D cavities. The flow in the cavity is described by the Navier-Stokes equations, the continuity equation and the energy equation. Turbulence is modelled with the kappa-epsilon model for which two extra convection-diffusion equations are added. The partial differential equations are discretized by using a finite volume method. For the pressure-velocity coupling the SIMPLE method is used. The equations are discretized on one vertical line in the calculation domain, after solution of the difference equations one of its neighboring lines is to be solved.
