Book Description
An experimental investigation was carried out in the hypersonic shock tunnel in which two diagnostic techniques, the cylindrical electrostatic probe and the electron beam density probe, were applied to flow field surveys in rarefied slightly ionized hypersonic flow. Their relative merits have been evaluated. It was found that both can be applied for flow field investigations and particularly, density tracing and mapping, provided that diffusion effects are nonexistent or negligible. In the course of this work, ion and neutral density profiles normal to a sharp flat plate and in the near wake of a 10 deg half angle cone were obtained. Also using flush electrostatic probes, the ambipolar diffusion flux of the ionized particles to the plate was measured. A comparison with theoretical results obtained using the Rudman-Rubin formulation for the hypersonic flow about a sharp flat plate modified for slightly ionized flow was carried out. (Author).

Book Description
An experimental investigation is reported in a hypersonic shock tunnel in which two diagnostic techniques, the cylindrical electrostatic probe and the electron beam density probe, were applied to flow field surveys in rarefied slightly ionized hypersonic flow. Ion and neutral density profiles normal to a sharp flat plate at M =18 were obtained. Also, using flush electrostatic probes, the ambipolar diffusion flux of the ionized particles to the plate was measured. A comparison with numerical results was obtained. In the viscous layer; large deviations were observed between the measured and calculated maximum density. No agreement was found to exist between ion and neutral density profiles normal to the plate.
