The enhancement of radiative heat transfer based on the multi-band feature of radiative gas is analyzed theoretically for the system of laminar channel flow of high-temperature CO2 and combustion gases between two parallel heat-absorbing surfaces. An integrodinerential equation of energy conservation, which takes into account the multi-band feature of the radiative gas, is solved numerically, and the enhancement effect by installing a solid plate in the radiative gas is calculated. From the results, it is shown that enhancements of local heat flux of up to 80% for CO2 and 36% for combustion gas are attainable. © 1988.
