Incompressible flow and heat transfer computations using a continuous pressure equation and nonstaggered grids

摘要

A pressure-based algorithm for incompressible flows is presented. The algorithm employs a finite-volume discretization in general curvilinear coordinates on a nonstaggered mesh. This approach is derived from a finite-element algorithm, and is here extended to the finite-volume/finite-difference context. The algorithm can be classified as a SIMPLE-like sequential method and is validated in two classical test cases: the lid-driven cavity and the differentially heated cavity problems, Good results, with no pressure checkerboarding, ave achieved up to Reynolds numbers Re=10(4) and Rayleigh numbers Ra=10(8), respectively.
