Analysis of Supercritical Hydrocarbon Fuel as a Coolant for Improved Thermal Performance of Scramjet

Supercritical hydro-carbon fuel is engaged in concurrent cooling of corresponding combustors to recover heat. The working fluid preferred for the analysis is methane because of its heat transfer characteristics and it works significantly at higher Mach numbers. The aim is to develop the thermal performance and the convection heat transfer properties of a regenerative cooling system in scramjet engine. The model or replica of the cooling channel is a complicated task because of its factors, including the high wall temperature gradients, values of high Reynolds number (Re), and developing the three-dimensional geometry of passages. The working fluid is incorporated into the rectangular channels model with the required inlet mass, inlet temperature, and pressures.
