Interaction of semi-confined turbulent jets: final report

Abstract

The report is concerned with the theoretical and experimental study of the interaction of semi-confined, subsonic, turbulent jets, the application of the results to fluidics being one of the primary objectives in mind. The theoretical results obtained both through the use of the free-streamline theory and a new momentum analysis for both the single and symmetric control-jet configurations are presented in the first part of the report. The second part covers the detailed experimental investigations of the jet deflection and the velocity-and turbulence-profile measurements obtained with a hot-wire anemometer for both the single-control-jet and summetric beam-deflection type amplifiers. Finally, the results of the two parts of the study are compared and the advantages and shortcomings of the various analyses are presented. (Author)
