Book Description
A theoretical and experimental investigation has been conducted of the pressure distribution on the surface of either a circular cylinder or a truncated cone located within the base region of another circular cylinder at Mach number 2. A similar analysis of pressure distribution was made for rearward-facing two-dimensional steps, and theoretical results were compared with experimental results of earlier investigations. Theoretical base-pressure ratios of two-dimensional steps agreed well with experimental results; however, as a result of the simplifying assumptions made for axisymmetric configurations, only a range of values for theoretical base-pressure ratio could be calculated within which the experimental results were expected to occur. The data generally followed the trends predicted by the theory, and deviations apparently could be explained.

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.
