Abstract
The energy equation describing nongray radiation transfer and simultaneous turbulent diffusion in a layer of molecular gas enclosed by parallel black walls is developed into a linear integral equation with symmetric kernel. The solutions for temperature and convective and radiative heat flux profiles are strictly valid for constant volume heat source, but are good approximations to those for established turbulent flow. The results show the effect of self-absorption by cold gas in the vicinity of the wall and the coupling between nongray radiation and turbulent diffusion. A correlation of the results in general dimensionless form makes it possible to calculate readily the effects of turbulent boundary layer blockage of nongray gas radiation from any of a number of common gases.
