Abstract

The characteristics of pulsatile flow with the reverse flow in the grooved channel are investigated experimentally. Three flow parameters are considered: the net flow Reynolds number, the oscillatory fraction of the flow rate and the oscillatory frequency. The flow structures are visualized using the aluminum dust method. It is observed that the flow tends to be more unstable in the deceleration phase for the pulsatile flow. Meanwhile, the experimental oscillatory fraction of the flow rate is easier to reach the theoretical value at lower oscillatory frequency. Furthermore, it is found that the oscillatory fraction of the local pressure decreases with the increase of the period of oscillation, and the oscillatory fraction of the downstream local pressure is larger than that of the upstream local pressure.
