Unsteady Shear Layers.

Abstract

An elliptic nozzle was found effective for entrainment in jets. It was found that the onset of the fine scale turbulence alters the characteristics of the vortex merging. These studies encompassed plane jets, plunging airfoils, elliptic jets with mass entrainment and impinging jets. Additionally, the 3-D vortical flow over a backward facing step was investigated. A second aspect of the project focused on the emulation of turbulent wall eddy structures, bursting processes and associated turbulent spots. These studies were expanded to encompass the effects of unsteady flow on the turbulent wall structure. Keywords: Boundary layers.
