A time-dependent numerical method is presented that provides direct, exact, and unified solutions for axisymmetric flows about blunt nosed bodies of essentially arbitrary shape. The differencing scheme used ensures that the required stabilizing terms can be specified arbitrarily small and completely independent of the finite difference mesh sizes used. The method is shown to be more accurate than other reported time-dependent techniques. Computational procedures are introduced to enhance the computer efficiency obtainable with the time-dependent method. Extensive comparison with standard computational methods shows that the present method is comparable in both numerical accuracy and computer efficiency. A FORTRAN IV computer code and instructions for its use are provided. Author
