Reynolds Number Scaling and Parameterization of Stratified Turbulent Wakes
Abstract
The work funded by this grant has examined both the turbulence and the internal wave field emitted by a stratified turbulent wake of a towed sphere over a range of body-based Reynolds and Froude numbers using implicit Large Eddy Simulation (LES). Work has been completed on the Lagrangian drift, and hence particulate dispersion, induced by a internal wave beam reflecting off a rigid lid surface in an idealized linear stratification. The far-field and surface signature of the internal wave field emitted by stratified turbulent wakes has also been examined. Simple predictor models linking surface-observed wavelengths to body-generating depth and passage time have been constructed .
