Abstract
The interaction between internal waves (IW) and small-scale turbulence is investigated in a laboratory tank with thermocline-type stratifica tion. Turbulence has been produced by an oscillating grid. Temperature and velocity measurements have been provided. The turbulent energy di stribution and the dependence of the TW damping rate on the wavenumber have been measured. The damping rates for TW, calculated based on a s emiempirical model for turbulence, demonstrate a quantitative agreemen t with experimental data.
