Abstract

Abstract:

The flow in a plane supersonic ejector is investigated numerically using a large eddy simulation (LES) technique. In order to validate the reliability of LES method, quantitative comparisons of the calculated result with experimental data are made including the velocity and temperature profiles. They show that the present computational results agree well with the experimental data, which indicates that the LES method can be used to study this problem. The instability processes of the primary jet in the ejector are the same as those of the free jet, which can be divided into three different stages, i.e., shear layer growth, instability and mixing. Distributions of the Lamb vector divergence indicate that the mixing process is restricted in a narrow zonal-area. Power spectral density analysis of pressure signals in the mixing section shows that the flow mixing process is dominated by the primary jet instability, and the characteristic Strouhal number is approximately 0.27.
