Consideration is given to the coupling of conduction and thermal radiation in the presence of viscous heat dissipation in Couette flow. Both the stationary and the moving walls are assumed to be diffuse, isothermal parallel surfaces a finite distance apart; the fluid between them emits and absorbs thermal radiation in a diffuse manner. The problem is formulated in terms of a nonlinear integrodifferential equation, and the solution is obtained by the method of Barbier. Numerical examples show the infiuence of the dimensionless parameters as well as the difference between the results for an opaque and a transparert moving wall. The effects of the temperature level, the optical thickness of the fluid, and th; emissivity of the walls on the temperature distributions, local radiant energy fluxes and heat transfer characteristics are investigated. The temperature profiles obtained by the approximate Barbier's method are compared with those calculated by a more exact method of reference, and the heat transfer results predicted by the two methods are also examined.
