Book excerpt: An experimental study was performed to determine the flow characteristics of a tabbed free jet. Results were acquired in the near field (nominally 2 tab widths upstream to 2 tab widths downstream of the exit plane) of a tabbed jet. Upstream pressure results showed static pressure distributions in both the x-and y-directions along the top surface of the tunnel. Hot-wire measurements showed rapid expansion of the core fluid into the ambient region. Two counter rotating regions of streamwise vorticity were shown on each side of the primary tab. An enhancement of the tabbed jet concept was proposed and tested. Specifically, two tabs, half the scale of the primary tab, were added to the primary tab to provide attachment surfaces for the normally occurring ejection of fluid. The secondary tabs caused a slight increase in the streamwise vorticity created from the upstream static pressure gradient while significantly increasing the re-oriented boundary layer vorticity. The combined pumping effect of the two counter rotating regions of vorticity caused a significant increase in the transport of the jet core fluid into the surrounding region. Bohl, D. G. and Foss, J.

This book was released on 1972 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretically, near-field pressure measurements in a turbulent flow can be used to predict far-field acoustic radiation. The basis of this study is the experimental verification of methods for obtaining the necessary data. Pressure intensity, spectra and cross-correlation data are obtained in three types of jet flows. The characteristic scale of pressure fluctuations is compared to the equivalent velocity scales. Consideration is given to errors associated with frequency response, low frequency cutoff and probe-turbulence interaction. Estimates of the various errors are given and certain correction procedures are suggested. (Author).
