An Experimental and Numerical Study of a Supersonic Overexpanded Jet Gas-Dynamic Structure

Experimental data about the structure of the supersonic overexpanded jet (Ma=3, n=0.58) is obtained. This data is intended for verification of numerical calculation results. Main factors influencing on the precision of experimental data are shown. Experimental results are supplemented with numerical simulation performed with program package ANSYS Fluent. Differences between experimental and numerical data are analyzed
