Abstract

Analyses and numerical procedures are presented to investigate the radiative interactions of absorbing emitting species in chemically reacting supersonic flow in various ducts. The two-dimensional time dependent Navier-Stokes equations in conjunction with radiative flux equation are used to investigate supersonic flows undergoing finite rate chemical reaction in a hydrogen air system. The specific problem considered is the flow of premixed radiating gas between parallel plates. Specific attention is directed in investigating the radiative contribution of H2O, OH and NO under realistic physical and flow conditions. Results are presented for the radiative flux obtained for different gases and for various combination of these gases. The problem of chemically reacting and radiating flows are solved for the flow of premixed hydrogen-air through a 10° compression ramp. Results demonstrate that the radiative interaction increases with increase in pressure, temperature, amount of participating species, plate spacing and Mach number. Most of the energy, however, is transferred by convection in the flow direction. In general the results indicate that radiation can have significant effect on the entire flow field.
