On the Mechanisms of Dimensional Transition in Stably Stratified Turbulent Fluid Layers
M. Caggio, T. Bodnár, M. Schiavon
Abstract:
The purpose of this short review communication is to present some recent results on the effects of stable density stratification on the three-dimensional turbulent dynamics of "thin" fluid layers forced at intermediate scales. In particular, how the strati cation and the confinement affect the mechanism of kinetic and potential energy transfer between different scales. Results on two-dimensional vertically stratifed flows and possible applications for stably stratifed atmospheric boundary layer will be shortly discussed.
Keywords:
"thin" fluid layers, stable density stratification, kinetic and potential energy transfer, atmospheric boundary layer
