Soviet Physics Uspekhi, 1970
The fundamental results of recent research on the propagation of elastic microwaves (hypersonic waves) in crystals of various types are considered. The procedure for experiments with hypersonic waves is briefly described. The characteristics of the propagation of elastic waves in crystals (polarization, velocity, energy flux) and methods of their ...

Apart from method of characteristic calculations, there has been little analytical consideration of high-speed internal flows where transverse curvature and/or viscous-inviscid interaction are important. Molder [1] has carried out a numerical computation for internal conical flow using the inviscid Taylor-Macoll equations; however, a singular ray is ...

An extension of classical hypersonic similitude is developed which takes into account the interaction effect of the displacement thickness of the boundary layer. A basic result of this viscous similitude is that the total drag including frictional drag obe}^s the classical similarity law for the pressure drag. Additional similarity conditions governing

The Interaction of a Hypersonic Plume with an External Hypersonic Stream
1973Abstract : A theoretical study of the gas dynamic interaction between a hypersonic plume and the opposed hypersonic external stream is presented. Steady, axisymmetric, inviscid, perfect gas flow is postulated for both the bow and far field regions.

Abstract The chapter starts its analysis with blunt-nosed bodies. In a supersonic flow, a blunt-nosed body produces a bow shock wave. The chapter shows that the shape of the shock and the entire flow between the shock and the body become independent of the Mach number, M∞, provided it is large enough.
