Abstract:

Inviscid flow about a blunted axisymmetric nose at a small angle of attack is treated by the simplified reflection principle of Garabedian, in order to transform the governing equations to a symmetric-hyperbolic system. A stable finite difference scheme is given and truncation errors presented whereby a Cauchy problem in the transformed space is derived for the inverse problem considered. In the transformed, higher dimensional space, body and shock are given as constant valued coordinates, which considerably simplifies subsequent numerical and theoretical considerations. A section on Friedrichs symmetric positive operators is included to illustrate the application of the method to the problem considered. Author
