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
