A finite-volume Navier-Stokes solver for multiblock structured meshes.

In this thesis numerical solution of 2D steady laminar incompressible viscous Navier-Stokes equations has been considered. For such flows a problem occurs with preserving mass flow through the system. Primitive variables were chosen to perform computations. The solver is based on the finite-volume approach with artificial compressibility. The code was written to accomplish numerical computations based on the suggested approach. This code is capable of handling multiblock meshes and does not require coordinate transformations, due to the finite-volume approach. The artificial compressibility approach allows the calculation of pressure and at the same time preserves mass flow through the system at the steady-state. This code was validated against known results for the driven cavity problem and rapidly expanding channel problem. The problem of a moving road vehicle was studied for different mesh arrangements to investigate the influence of boundary conditions together with mesh quality on the computational results. The results of these calculations were also compared to those obtained by STARCD and found to be in reasonably good agreement.Dept. of Mathematics and Statistics.
