Abstract
This paper presents the results obtained from numerical and experimental studies of supersonic jets coming out from convergent - divergent conical nozzles. In the numerical calculations, the two-stage Runge-Kutta time-stepping scheme is applied assuming inviscid, axially symmetric How. Effects of Macb number and exit to ambient pressure ratio on shock cell lengths are investigated with the aid of schlieren pictures and density contour plots. A parameter [β2/(M2 e−1)]; has been employed to characterize the distribution of pressure along the jet axis which makes them invariant of the exit to ambient pressure ratio. The agreement or numerical results with the experimental data validates the applicability oT numerical analysis for predicting structure of supersonic axisymmetric free jet flows.
