Unstructured triangular mesh generation techniques and a finite volume numerical scheme for slider air bearing simulation with complex shaped rails

摘要

Three different mesh refinement and adaptation techniques based on the Delaunay method are used to generate quality unstructured triangular meshes over air-bearing sliders with complicated rail systems. A fully implicit finite volume scheme is formulated to locally integrate the generalized Reynolds equation. The resulting simultaneous equations are solved by point Gauss-Seidel iterations. The scheme is unconditionally stable. The efficiency of the scheme is greatly improved by the implementation of a non-nested multi-grid technique.
