Jet Pump Assembly Having Increased Entrainment Flow

摘要

A jet pump assembly (200) according to an example embodiment of the present invention includes an inlet body (202) arranged in proximity with a throat structure (214) so as to provide an entrainment entrance between a discharge end (208) of the inlet body (202) and the throat structure (214). A drive flow (402) of a motive fluid is supplied at a first velocity to the inlet body (202) and is discharged through at least one nozzle (212) at a higher second velocity, thereby creating a pressure drop in the throat structure (214). The pressure drop facilitates a first entrained flow (406) of suction fluid into the entrainment entrance and a second entrained flow (408) of suction fluid through at least one channel (210) passing through the inlet body (202). The at least one channel (210) is configured such that the second entrained flow (408) is isolated from the drive flow (402) while passing through the inlet body (202).
