One dimensional unsteady gas flow analysis applied to pulsing combustor systems.

Abstract

A novel program for the solution of one dimensional unsteady gas flow by the field method of characteristics is developed. It is shown how this was used as a design tool to make a simple pulsing combustor with associated fuel system. The results from running the actual combustor are used to refine assumptions used in the program. It is shown that qualitative agreement can be achieved between predicted and measure pressure waveforms. A design of collector/smoother is suggested and this design is tested and the results compared with a computer prediction. Again good waveform agreement is achieved. The experimental and computed results are used to suggest design improvement.
