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