Abstract: One of the main features of the backwardfacing step (BFS) low frequency pulsatile flow is the unsteadiness due to the convection of vortical (coherent) structures, which characterize the flow dynamics in the shear layer. ...

Abstract: This work is concerned with the behavior of pulsatile flows over a backwardfacing step geometry. The paper mainly focuses on the effects of the pulsation frequency on the vortex development of a 2:1 backwardfacing step for ...
