For many purposes, such as heat transfer calculations, the local flow conditions at the outer edge of the boundary layer must be known. These conditions are different from the free stream conditions ahead of the body because the flow passes through a shock wave. They will also vary in the region between shock wave and body surface if the streamlines are not parallel, as in the case of three-dimensional flow.nThe ratio of local to free stream conditions versus free stream Mach number has been plotted up to M = 20 for pressures, densities, velocities, Mach numbers, and temperatures. The graphs represent a compilation of available data. They have, however, either been published in a limited Mach number range only, or in a form not always suitable for practical application.nReleased by author 17 April 1957
