Measurement of Turbulent Correlations in a Coaxial Flow of Dissimilar Fluids.
Abstract
The importance of coaxial jet flows has led to much investigation in the field. In this work axial turbulence intensities in a coaxial flow of dissimilar gases are presented. The system consisted of a circular freon 12 stream issuing into a faster and much larger air stream. The air-freon 12 density ratio is 1/4. The velocity ratios ranged from 40:1 to 5:1 with an absolute air velocity not exceeding 56.0 ft/sec. The system is assumed to be incompressible and no appreciable temperature variation was observed. Measurements were made with hot-film anemometers. An aspirator probe and a parallel film probe were used. These probes were controlled by two independent constant temperature channels.
