Finite volume methods for incompressible flow
Darryl Whitlow
Abstract
Two finite volume methods are derived and applied to the solution of problems of incompressible flow. In particular, external inviscid flows and boundary-layer flows are examined. The firstmethod analyzed is a cell-centered finite volume scheme. It is shown to be formally first order accurate on equilateral triangles and used to calculate inviscid flow over an airfoil. The second method is a vertex-centered least-squares method and is second order accurate. It's quality is investigated for several types of inviscid flow problems and to solve Prandtl's boundary-layer equations over a flat plate. Future improvements and extensions of the method are discussed.
