Abstract:

The objective of this project is to further enhance the characterization of the Simulated Turbulence and Turbidity Environment SiTTE. The numerical model emulates the Rayleigh-Benard laboratory tank at NRLSSC, which allows variation of turbulence intensity. This provides the framework for repeatable experimental conditions in a controlled setting. fu support of the 6.1 newstart project DOLFIN aimed at active boundary layer control for drag reduction, we implemented a numerical tank representation of a laminar to turbulent flow tank, a new acquisition at NRLSSC. To advance our understanding of Langmuir-type near surface coherent structures and associated turbulence, we refined experiments in the numerical tank emulating the SUSTAIN laboratory facility at the University of Miami with the goal of reproducing experimental conditions encountered during the laboratory work.
