Abstract

A three-dimensional inviscid flow computation was made on a dual mode scramjet inlet model that had been tested in the wind tunnels. An Euler solver based on a high accuracy total variation diminishing scheme was used to carry out the analysis. The objective was to establish three-dimensional scramjet inlet computational fluid dynamics capability and to evaluate the applicability of Euler solutions for inlet performance calculation. The computations were made for freestream Mach numbers 2 and 5. A postprocessor was developed to calculate the inlet performance. Comparison between computed and available test data showed the Euler analysis was able to predict the trend of the inlet performance and provide insight of the flowfield.
