Experimental investigation of planar offset attaching jets with small offset distances

Experimental investigation of planar offset attaching jets with small offset distances An experimental investigation was performed to characterize the development of planar jets initially issuing parallel to an adjacent wall with offset distances of up to 1 jet height and Reynolds number of 44,000. The results showed that the initial development of the mean flow field in the planar offset jets could be divided into five regions; three associated with the jet attaching to the wall similar to other reattaching shear layer flows and two associated with the resulting planar wall jet flow. The transition from the reattaching flow to the wall jet flow was also characterized by a significant change in the characteristic frequency, size, and convection velocity of the large-scale structures in the flows. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

An experimental investigation was performed to characterize the development of planar jets initially issuing parallel to an adjacent wall with offset distances of up to 1 jet height and Reynolds number of 44,000. The results showed that the initial development of the mean flow field in the planar offset jets could be divided into five regions; three associated with the jet attaching to the wall similar to other reattaching shear layer flows and two associated with the resulting planar wall jet flow. The transition from the reattaching flow to the wall jet flow was also characterized by a significant change in the characteristic frequency, size, and convection velocity of the large-scale structures in the flows.
