Book Description
Velocity profiles at five axial stations in the half-jet mixing region of Mach 0.7, 0.85, 0.95, 1.49, and 1.96 free jets were measured. The nondimensional velocity distributions are similar, and correlate with the theory of Crane for incompressible flow. The half-jet spreading rate is essentially constsnt at subsonic speeds and decreases at supersonic speeds. The variation of jet spreading parameter with Mach number was determined from correlation of these and other data.

Book Description
Recent attempts to predict the heat transfer from a high enthalpy, compressible free jet impinging upon surfaces in its path have suffered from a complete lack of knowledge concerning the behavior of turbulent jets of dissociated gases. Although it had been assumed that high enthalpy gas streams would exhibit the characteristics of cold jets, which have been subjected to extensive study, there had been no experimental evidence to support this contention. A research program was conducted to determine radial and axial variations in fluid properties, i.e., velocity, density, enthalpy, etc., in compressible free jets of dissociated gases produced by electric-arc plasma generators. Experimental investigations were confined to the near flowfield of the jets, since 90 percent of change in jet fluid properties, from their initial values at the arc nozzle-exit plane to the properties of the ambient fluid, was accomplished within 40 nozzle radii from the jet origin. Heat-transfer rates from these jets, when impinging upon a flat surface perpendicular to the jet axis, were determined experimentally. Correlation of this data could then be accomplished by means of a relationship similar to those for stagnation-point heat transfer to blunt bodies in a uniform stream when local jet properties were employed.

Book Description
The turbulent mixing of confined axisymmetric incompressible jets was studied, using the turbulent boundary layer equations in terms of transformed von Mises variables, with semi-empirical formulations of the turbulent transport coefficients. The solution was obtained by the method of finite differences. Analytical predictions of the jet mixing flow fields were obtained for several configurations, covering a resonably wide range of values of the problem parameters. A turbulent mixing model which satisfactorily predicts mean flow profiles for a reasonably broad spectrum of flow conditions has been formulated.
