Solving the incompressible Navier-Stokes equations requires special care if the velocity field is not discretely divergence-free. Approximate projection methods and many pressure Poisson equation methods fall into this category. The approximate projection operator does not dampen high frequency mode
It is commonplace in 2D fluid dynamics that intense large-scale vortices arise during turbulence decay. Both the largescale vortex and the turbulent components will be important in the further evolution: the vortices will modify the turbulent dynamics and, in turn, will be modified by the turbulence
Hot-wire anemometry measurements over a heated flat plate are made for three different temperature difference cases of 10, 15, and 2OC. Space-time correlations of temperature fluctuations T' are determined from which mean convection velocities, mean inclination angles, extent in space, and coherence
