The Generation and Radiation of Supersonic Jet Noise. Volume VI. Jet Flow Measurement and Analysis with Special Emphasis on Remote Sensing Devices. Crossed Beam Schlieren, Laser Doppler Velocimeter, Pulsed Laser Interferometer.

Abstract

The report describes three remote sensing devices developed to measure jet exhaust fluctuating density gradients, mean and turbulent velocity and mean temperature are described. These instruments are a crossed-beam schlieren, a laser Doppler velocimenter, and a pulsed laser interferometer. A jet turbulence facility was developed, along with five 2 inch diameter jet nozzles (one convergent and four con-div, up to Mach 2.0), for the purpose of providing laboratory controlled conditions, in order to properly evaluate the remote sensing instruments.
