Experimental and Numerical Study of H2O/ CO2 Vitiation Effects on Ethylene/ Kerosene-Fueled Dual-Mode Scramjet Combustor Performance
Experiments for the direct-connect, dual-mode, hydrocarbon fueled scramjet engine with one/two cavities were conducted in the Northwest Polytechnical University Supersonic Combustion Facility to compare the combustor performance under clean air and air vitiated with H2O/CO2 conditions. The primary objective was to understand the complicated issues with regard to the effects of airstream vitiation on scramjet test performance. A set of comparative combustion tests were carried out under the same test gas parameters of nominal Mach 2.0, total temperature of about 800K and total pressure of about 780kPa. The comparative experiments results show that contaminants of inflow decrease wall pressure. Then, massively parallel CFD simulations of reacting flowfield in the combustor under same experimental conditions were conducted using flow solver AHL3D. The final objective was to develop computational capabilities with AHL3D to aid current hypersonic researches and provide insight into the detail combustion flow which was not resolved by the available instruments.
