Abstract:

An analysis of the fluid mechanics of wakes behind bodies in hypersonic flow is presented. The models used for idealizing both the flow field and the chemistry of air are discussed first. The fluid mechanics of the wake itself is then shown to be describable in terms of transformed coordinates which are applicable to both laminar and turbulent wakes. The transformation to the physical plane requires description of the transport properties of the gas these are therefore discussed next. In this connection a rational means for estimating the turbulence transport properties is described. Finally, there are presented the results of numerical analysis of four cases which appear to lead to the highest concentration of electrons in the wake and of the initial conditions for a boundary layer induced wake.
