HEAT TRANSFER DUE TO COMBUSTION ON A FLAT PLATE IN SUPERSONIC FLOW
Abstract
A theoretical and experimental investigation was undertaken of heat transfer effects at the surface of a flat plate on which combustion is occurring in a supersonic air stream. A simplified theoretical model is developed which leads to expressions for the heat transfer coefficient and heat transfer rate at the surface. The experimental technique used to obtain heat transfer parameters is described. The experimental tests were conducted at Mach number 3.1 using the pyrophoric fuel triethylaluminum. A comparison between the theoretical and experimental results indicates that the former yields order-of-magnitude estimates of the heat transfer coefficient and rate which are satisfactory for purposes of engineering design. The theory is then used to obtain estimates of heat transfer parameters at the surface of a cone-shaped interceptor executing a coast trajectory. The results are shown to be well correlated by an empirical expression similar to that encountered in the literature for turbulent non- reacting flow over flat plates having both constant and variable surface temperatures.
