EXPERIMENTAL STUDY OF WIND-DRIVEN COUNTERCURRENT FLOW.
Abstract
The subject matter of this currently ongoing doctoral research project is an in-depth inquiry into the physics of wind-driven water currents in lakes and small ocean bays. The particular flow under consideration is two-dimensional in a vertical plane, comprising a shear-induced surface current in the direction of the wind, and an opposing gravity-driven current near the bottom. Under turbulent conditions, i. e. , for flow at a Reynolds number above some as yet unknown critical value of laminar-to-turbulent transition, the unique countercurrent flow combines elements of both wall and free turbulence, and the thereby entailed intense mixing can be expected to have a significant bearing on the ecological quality of the water bodies.
