It would therefore seem that the nonlinear interaction between inviscid and centrifugal instabilities is an important problem to be considered in the hypersonic limit.
The instability of a compressible flow past a wedge is investigated in the hypersonic limit.
This is a useful generalized account, serving as an introduction to the short discussion of hypersonic propulsion that is given later.
The amplitude of a disturbance must be quite small in order for linearization to be valid in hypersonic flows.
However, at hypersonic speeds and therefore with high temperatures near the body, the assumption of equilibrium flow becomes questionable.
Detailed calculations are given showing the use of such a compressor to heat air for use in a hypersonic wind tunnel.
A final section reviews recent work on needle-likebodies in viscous hypersonic flow, and gives a formulation of the three-dimensional interaction problem.
It is possible to derive a hypersonic similarity rule from these considerations.
The inviscid flow behind a cylindrical blast wave and its analogy with hypersonic flow past blunt-nosed cylinders is considered.
The volume attempts to present an integrated picture of recent work in hypersonic gas dynamics.
The problems discussed below provide a testing ground for the hypersonic expansion method and give insight about its range of applicability.
Once these reference solutions have been established, the hypersonic equations are attacked by a variety of methods.
An experimental investigation of the hydrodynamic stability of the laminar hypersonic boundary layer was carried out with the aid of a hot-wire anemometer.
The nozzle expands the shock-heated test gas t o a design area ratio of 16, producing hypersonic flow in the test section.
The work is motivated by recent interest in the development of hypersonic vehicles.
