RESUMO

Numerical solution of two-dimensional equations of combined heat transfer in the compressible boundary layer approximation for a uniform radiating and absorbing gas (hydrogen with addition of lithium), given the spectral dependence of the absorption coefficients and actual properties of the working body, has been used as the basis for investigation of combined heat transfer in the initial areas of high-temperature outlet channels and nozzles (using as examples nuclear missile engines (NME) and nuclear power plants (NPP) with a gas-phase reactor) in variable and strong injection for laminar and turbulent modes of flow. It has been shown that intense injection results in a significant reduction of heat fluxes to the wall and is an effective means for protection of walls against high heat fluxes, especially convective ones. Also, the effect of radiation on the formation of temperature profiles and on heat fluxes has been studied. Recommendations on the application of simpler computing techniques are given.
