Laser-Induced Fluorescence/Particle Tracking System for Stratified Flow Research
Abstract
The research conducted has two components. In the first part, a model that deals with turbulent mixing across sharp density interfaces subjected to homogeneous turbulence was developed. The analysis was essentially based on the rapid-distortion-theory approach of Hunt, which reckon on the empirical observation that the dissipation rate of turbulent kinetic energy above an interface is independent on the height z. The homogeneous turbulence was modeled using the classical von Karman spectra and the interfacial motions were assumed to be governed by the linear internal-wave equations. It was further assumed that the first mode of internal waves governs the interfacial motions, thus simplifying the interfacial boundary conditions; the latter have been a major difficulty in modeling fluid motions near sharp density interfaces.
