An Experimental Investigation of Pulsating Subsonic Flow in a Conical Nozzle.

Abstract

Amplitude and phase relationships between sinusoidal pressure disturbances in the exit plane of a conical nozzle and mass flux response were experimentally determined for the subsonic flow of air in the nozzle. The experimental results were compared with values predicted by using the modified asymptotic Wentzel, Kramers, Brillouin method. Experimental measures were made with a constant temperature hot wire anemometer and a condenser microphone. Disturbance frequencies from 20 to 250 Hz were investigated for Mach numbers up to .34.
