Abstract

The numerical and experimental studies of the role of bottom friction and fluid layer depth on decaying quasi-two-dimensional turbulence enable several interesting observations. The numerical simulations showed that the evolution of vortex statistics of decaying 2D turbulence with bottom friction can be described by bottom-friction independent power laws. In the latter regime, the computed data showed a strong bottom-friction dependence and are strongly dominated by lateral diffusion.
