Boundary-layer and inverse potential-flow methods for axisymmetric bodies

This report provides a description of two methods and their computer programs for calculating viscous and inviscid flows past axisymmetric bodies. The first is a boundary-layer method for both laminar and turbulent flows. The procedure embodies a finite-difference representation of the boundary-layer equations and uses an eddy-viscosity model to represent turbulent flows. The second method is an inviscid-flow procedure which obtains solutions to the potential equation by an orthogonal expansion procedure. The accuracy is equivalent to higher-order Neumann solutions, but at a considerable savings of computer time. This method can be used in either a direct or an inverse mode. Details of each method are presented and the use of the computer program is documented with various test cases.
