Analytical investigation of transient diffuser wave phenomena.

Analytical investigation of transient diffuser wave phenomena.

A computer program was developed to solve the quasi-one- dimensional, unsteady flow problem associated with starting phenomena in various nozzle-short diffuser combinations of interest to gas dynamic lasers. The program was based on the techniques developed by George Rudinger in his book, Wave Diagr...
