An Exact Velocity Potential Solution of Steady, Compressible Flow Over Arbitrary Two-Dimensional and Axisymmetric Bodies in Simply Connected Fields
Abstract
This report discusses the use of the automatic numerical generation of curvilinear body fitted coordinates to solve the exact velocity potential equation for steady, compressible flow over two-dimensional and axisymmetric bodies in simply connected fields. A system of partial differential equations consisting of a Poisson equation for each coordinate direction is used to numerically generate the coordinates. A new, fast method of evaluating non- homogeneous terms for application to the Poisson generation system helps to make the coordinates more orthogonal. The use of these curvilinear coordinates allows the exact velocity potential equations to be easily applied to diverse body shapes and boundaries. (Author)
