Effect of Radiative Heat Transfer on Composites Thermal Environment
This paper compares the inner flow with the outer flow thermal environments in the supersonic rectangle turbulent duct and arc heater. The cold-wall heat flux is measured and the material is tested in two kinds of thermal environments. Due to the effect of radiative heat transfer, the cold-wall heat flux of inner flow is respectively higher 21％ and 40％ than that of outer flow in two kinds of representative flow conditions, and when the cold-wall heat flux increases, the effect of radiative heat transfer will gradually decrease. In material test experiment, the surface and rear temperatures of the composites in the inner flow are respectively higher about 400 ℃ and 90 ℃ than those of the same one in the outer flow.
