Hot-Wire Measurements in a Radial Turbulent Jet

Abstract

Results from hot-wire measurements in an approximate radial turbulent incompressible jet of air are reported. In the range of measurements, the jet did not attain a self-preserving form. The mean velocity profiles at various radial locations were quite similar, while the mean-square turbulent velocity profiles were similar only away from the jet center plane, and the lateral intermittency distributions were highly dissimilar. Data for the energy balance of the turbulent motion were obtained at a convenient downstream location.
