J. Fluids Eng. November 2014, 136(11): 111105.
Paper No: FE-13-1406
Published Online: September 4, 2014
... pulsatile flow is the unsteadiness due to the convection of vortical (coherent) structures, which characterize the flow dynamics in the shear layer. The physics of the flow field is analyzed by looking at energy redistribution between the mean and pulsating flow field obtained via a particle image...
