Abstract
A water hammer mitigation device includes an inlet, an outlet, an expansion housing, and a deflector. The inlet receives fluid from a source. The outlet passes the fluid to a destination. The expansion housing is disposed between the inlet and the outlet. The expansion housing defines an internal expansion chamber having an expansion volume sufficient to hold a plurality of volume units of the fluid. Each volume unit is defined by a fluid flow volume over a duration of time. The deflector is disposed within the expansion chamber. The deflector substantially redirects a backward energy pulse, which enters the expansion chamber through the outlet, away from the inlet.
