Abstract
An oil-cooled, gas-fired cylindrical test furnace was constructed to investigate the radiative and total heat-flux distributions at the circumferential sink wall. The furnace was instrumented such that flow patterns, gas-concentration profiles, temperature distributions, and radiative and total heat-flux distributions could be measured directly. Some typical examples of each of the above measurements are presented and discussed. The radiative heat-flux distribution at the sink wall has been calculated by dividing thefurnace enclosure into a number of uniform elements and simulating the radiative transfer by the Monte Carlo Method. The distributions calculated on the bases of measured temperatures within the furnace, or a measured flow pattern and gas-concentration patterns within the furnace, were found to agree well with the experimental data.
