Chemically Reacting Multi-Nozzle Plume Flows

Abstract

The computation of a 3D chemically reacting multi-nozzle plume from a 4-nozzle cluster has been undertaken using the Navier-Stokes solver TINA. The chemical composition of the plume consisted of CO, CO2, O1, O2, OH, H, H2, H2O, N2, Cl and HCl, with a Mach 3.8 outer freestream air flow. The technique of space-marching was used to speed up the computation in regions of fully supersonic flow. Results indicate significant levels of thermodynamic non- equilibrium in the regions of the mixing layer between the edge of the plume and the freestream air flow. In addition, marked 3D features are observed in shock shape and in general flow properties due to the interaction of the individual plumes from each of the four nozzles.
