"Radiant interchange between non-isothermal, gray diffuse surfaces with non-uniform radiosity has been determined for a rectangular cavity. Temperature distribution and heat flux as thermal specifications for the parallel surfaces of the cavity have been considered separately. Ambarzumian's method has been used for the first time to solve a radiant interchange problem. According to the method, the integral equation for the radiosity is first transformed into an integro-differential equation and then into a system of ordinary differential equations. Initial conditions required to solve the differential equations are the H-functions. The H-functions represent the radiosity at the edge of the cavity for various temperature profiles. Applying Ambarzumian's Method a closed-form expression for radiosity and heat transfer are obtained in terms of universal functions. Heat transfer from the cavity can be determined without knowing the radiosity inside the cavity. The numerical results for the H-functions, radiosity, local heat flux, overall heat transfer, local and overall apparent emittance for the cavity have been presented in the form of tables and graphs"--Abstract, page iii.
