An Experimental and Theoretical Study of Internal Waves Generated by the Collapse of a Two-Dimensional Mixed Region in a Density Gradient

Abstract

Previously reported experiments with a self-propelled body submerged in a fluid with a stable vertical density gradient have demonstrated that the turbulently mixed wake first expands more or less uniformly and then collapses vertically while continuing to expand horizontally. It was also shown that the vertical collapse of the wake generates internal waves. The present paper reports new experimental measurements and a linear theoretical analysis of the internal wave field created in stratified water by a burst of submerged turbulent mixing.
