Vortex Structure and Fluid Mixing in Pulsatile Flow through Periodically Grooved Channels at Low Reynolds Numbers.

A study of vortex structure and fluid mixing in pulsatile flow through grroved channels by numerical simulation and experimental flow visualizations is presented. The simulations correspond to experiments for pulsatile flows with / without flow reversal in two grooved channels with different cavity lengths, with Reynolds and Womersley numbers in the ranges of 46.8
