DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKTurbulent coaxial air-air mixing and hydrogen-air mixing were studied. The ratio of outer stream to jet veolcity was varied from 0.12 to 1.52 for the air-air mixing systems and from 0.16 to 0.42 for the hydrogen-air systems. Special emphasis was placed on the determination of the turbulent transport properties (especially the eddy viscosity and the Prandtl number) from the mean flow field measurements by use of an integral technique. Radial and axial profiles of velocity, concentration, shear stress, and eddy viscosity are presented, as well as radial profiles of the turbulent Prandtl number and representative static pressure profiles. In addition to the graphical presentation of the data, the mean flow field properties are presented in tabular form. The major conclusions of this investigation are: (1) the experimental technique used produced good quality meanflow field data; (2) the integral technique used for calculating the turbulent transport properties from the mean flow field data gave satisfactory results; (3) for the air-air system, a significant radial variation of the second regime eddy viscosity was observed for most of the tests; (4) the eddy viscosity decreases with increasing radius for the hydrogen-air systems; and (5) approximate average values for the turbulent Prandtl number are: 0.60 for the air-air tests and 0.80 to 0.85 for the hydrogen-air system.
