Abstract:

The growth of the turbulent core in the constant pressure wake, of a blunt hypersonic body is predicted by means of a mixing length theory. Near the body where the core is smaller than the enthalpy wake the constant density theory of Townsend is applied. A variable density solution is obtained for the region in which the core and enthalpy wake are of the same size. The two solutions are fitted to predict velocities, temperatures, and concentrations in the constant pressure region for several thousand body diameters behind the missile.
