Abstract

A study has been made of a pair of swirling jets having opposite rotation. Mean flow and turbulent intensity measurements were obtained and characteristics of the spreading rate determined. The swirling component of mean velocity decayed rapidly in the streamwise direction and by about 35 dia, the flow had most of the characteristics of the single, free jet without swirl. A linear superposition was found to be of limited application near the jet source but gave reasonable results in the developed flow downstream. It was observed that the major and minor axes of the flow, defining the asymmetrical cross-sectional shape, underwent a reversal of position as the flow progressed downstream.
