Publisher: American Society of Mechanical Engineers
Paper No: PVP2020-21069
... Abstract In some situations, it is possible for flow to go backwards through a pump during a transient waterhammer event. Sustained reverse flow will lead to reverse rotation. Understanding and predicting the pump behavior during waterhammer under these conditions is typically accomplished...
