Abstract
A new laboratory measurement technique is used to directly simulate the time evolution of stratified flows in a rotating fluid. The technique Direct Laboratory Simulation (DLS) relies on getting the Reynolds number from the length scale while keeping the velocity small, hence providing a characteristic time scale that is sufficiently large to permit full 3D scanning through the measurement volume in a relatively short time. 3D measurements of the vorticity and internal wave fields associated with a stratified vortex dipole are made. The structure of the enstrophy field is followed in time and the energy dissipation budget is balanced for times greater than Nt-30.
