Abstract:

In 1981-1983 a computer program was developed which solves numerically two-dimensional Euler equations using the Godunov method. The program was intended primarily for turbomachinery application, but with modification to the boundary conditions, application to any problem which is modeled by the Euler equations is possible. This report covers one year of extensive testing of the code for different flow regimes. This testing was done with three main objectives a To gain experience in simulation of the various problems related to the research activity in the Turbopropulsion Laboratory, Naval Postgraduate School, Monterey, California b To test code accuracy by comparing numerical with analytical solutions and c To find the source of errors for various numerical simulations and the basic Godunov method in order to reduce these errors.
