An Experimental and Numerical Study of A Supersonic-Jet Shock-Wave Structure

Abstract

The investigation of the shock-wave structure and numerical characteristics of supersonic-jet shear layer is of great importance due to numerous applications of supersonic jets in aerospace engineering. In the present work, a detailed study of a supersonic non-isobaric jet aimed at validation and further development of numerical algorithms for jet flow prediction has been carried out. The difficulties in numerical simulation of supersonic non-isobaric jets stem from the necessity of accurate resolution of various flow scales and from the occurrence of multiple shock waves and subsonic pockets interacting with each other.
