摘要：

Nozzle-flow characteristics. Duration of uniform flow and wall boundary-layer growth have been measured in the conical nozzle of a reflected-shock tunnel operating at high- enthalpy conditions. Experiments were performed in air for shock-tube Mach numbers of 16. 5 and 11. 5, with corresponding initial driven-tube pressures of 0. 5 and 10. 0 torr, respectively. Several different diagnostic techniques were used. Radiation-intensity and electron- density measurements were found to be the most sensitive flow indicators. Measured boundary-layer and displacement thicknesses are compared with the results of two typical prediction techniques.
