| Research Abstract |
A pulsating simulated blood flow has been experimentally and numerically examined in order to evaluate the inevitability of pulsation in blood flow from a viewpoint of efficiency in blood supply. In the acceleration period, the drag reduction rate increases and re-laminarization process is induced with decreasing the amplitude of the mean pressure gradient in the acceleration phase with the longer acceleration period. As for the deceleration period, the drag reduction rate increases with larger negative mean pressure gradient in the deceleration period with the shorter deceleration period.
