• In order to provide some insight into problems of heat transfer by simultaneous radiation and conduction, heat transfer in a Couette flow with a medium absorbing and emitting thermal radiation is investigated theoretically and experimentally. Numerical solutions are obtained for a radiant medium whose heat conductivity and absorption coefficient are linear with temperature. Approximate solutions for optically thin media are obtained by replacing the kernel of the radiation-integral term in the fundamental equation with a quadratic expression. The regions of the total heat flux where both radiation and conduction should be considered are shown in a figure by a curved surface in three-dimensional coordinates system and the total heat flux turns out to be approximately the sum of the heat flux due to radiation calculated by neglecting other mechanisms than radiation and that due to conduction calculated by neglecting radiation. Some experimental studies have been made by generating a Couette flow between two concentric cylinders with the inner cylinder rotating and heated, and the outer at rest and cooled, where carbon-dioxide is used as a radiant medium. Experimental results are in good agreement with theoretical ones.
