INVESTIGATION OF THE MIXING OF PERPENDICULAR GAS JETS AS APPLIED TO SUPERSONIC COMBUSTION.
Abstract
An experimental investigation of the turbulent mixing of subsonic, sonic, and supersonic jets of helium discharging transversely into a supersonic jet of air was made using a two-dimensional mixing chamber. The investigation has a potential application in the field of the supersonic combustion ramjet engine. The Mach numbers of the helium jets were 0.75, 1.0, and 1.5, respectively, and the Mach number of the air jet was 1.5. Both the helium and air jets had stagnation temperatures of approximately 76F. The effects of combustion on the mixing were not considered. Volumetric concentration values and total pressure values were obtained at points in the mixing region, and helium volumetric concentration profiles were plotted. Schlieren photography was used to obtain a visualization of the flow structure. Sonic injection was found to be the most desirable method of injection due to depth of penetration and total pressure considerations. (Author)
