Abstract:

The report covers experimental work performed to determine the effect of nozzle divergence angle, specific heat ratio and plug nozzle configuration on turbine nozzle performance. Off design performance was the primary area of investigation. The effect of nozzle divergence angle was investigated with conical and contoured nozzles for two Mach numbers over a range of speed and pressure ratios. The performance of selected plug nozzle geometries was neasured over a range of speed and pressure ratios. The influence on performance of the gas specific heat ratios was experimentally determined by testing the same nozzle with gases of different specific heat ratios. The reduced experimental data is presented in tabular form as well as graphic presentation in several formats.
