Flow structure and nonequilibrium processes during mixing of nonparallel supersonic jets
Abstract
Turbulent mixing between a periodic array of 920-micron-half-height CO2(0.96)-H2O(0.04) jets emerging from 10-deg-flare-angle wedge-shaped nozzles at CO2-mode vibrational temperature 300 K and velocity 939 m/sec and a 1.61-mm N2 jet emerging from a specially shaped nozzle at 2000 K and 1878 m/sec is investigated by means of a numerical simulation, applying the techniques of Volchkova et al. (1980). The isobars in the initial part of the flow and the profiles of pressure and gain are shown in graphs, and significant differences between parallel and nonparallel mixing are noted for flow pattern and gain but not for output energy.
