An experimental study is presented of the turbulent mixing of two coaxial air jets at subsonic-supersonic speeds in a closed duct. The investigation was undertaken to obtain velocity profiles and axial velocity decay results and other turbulent flow properties with existing PIBAL equipment, and to analyze the conditions needed for an improved experiment. By using a suitable total pressure it was possible to correctly expand the ducted outer jet to ambient conditions. Negligible pressure gradients were found in a considerable region of the duct and all static and stagnation pressure measurements were made in the regime. The axial velocity decay was thus determined. On the basis of the pressure measurements the flow field was divided into three mixing regions. In each of these regions the normalized velocity and total pressure profiles were correlated with values of the axial and radial coordinates. Jet boundaries were measured and an eddy viscosity function calculated. Detailed recommendations are made for improvements of this type of experiment. (Author).

The free turbulent mixing of a supersonic jet was investigated with an interferometer, of which a description is given. Density and velocity distributions through the mixing zone were obtained. The velocity distribution was found to be similar to those for imcompressible jets over only the subsonic portion of the mixing pattern.

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).
