Abstract:
1. A water hammer mitigation device for redirecting a backward energy pulse, the water hammer mitigation device comprising: an expansion housing including an inlet, an outlet, and an interior housing surface, wherein the interior housing surface of the expansion housing defines an internal expansion chamber; a deflector within the expansion chamber, the deflector fixedly mounted to a portion of the interior housing surface, the deflector including a fixed convex surface that substantially faces toward the inlet, the deflector including a fixed concave surface to define a concave volume wherein the concave volume is bounded between the outlet and the inlet by the fixed concave surface and opens in a direction substantially toward the outlet, wherein an end of the outlet extends into the concave volume of the deflector, and wherein the deflector is configured to substantially redirect the backward energy pulse, which enters the expansion chamber through the outlet, away from the inlet; and a dampener in fluid communication with the expansion chamber, wherein the fixed concave surface of the deflector is aligned to redirect the backward energy pulse at least partially toward the dampener to absorb at least a portion of the backward energy pulse.
