Modeling and Control of Large Eddies Generated by Maneuvering Self-Propelled Bodies in Stratified Fluids
Abstract
Our experiments and theoretical analysis show that when a submerged self-propelled vehicle makes a maneuver in a stratified fluid, e.g., accelerates/decelerates or changes the direction of its motion, this leads to the formation of unusually large horizontal eddies of the size of up to several kilometers and with decay times of several days. It is also shown that for vertical background shear typical for the upper ocean, the shear itself only partly suppresses the eddy formation and reduces their decay times, which still remain significantly large. Such eddies may have potentially important applications for submarine detection and have not been studied previously.
