Patent ID: 8505310

Claim:
An ejector system for combining a high pressure fluid flow stream with a low pressure fluid flow stream comprising; a nozzle chamber in communication with a high pressure fluid flow stream having an inlet and an outlet; a suction chamber in communication with a low pressure fluid flow stream having an inlet, an outlet and configured to receive the outlet of the nozzle chamber therein; the outlet of the nozzle chamber defining multiple nozzles and a central axis, the multiple nozzles each having an outlet end that includes a series of undulations, and wherein the high pressure flow stream exits the nozzle chamber to define multiple flow streams having multiple surface areas for interlayer drag between the multiple high pressure flow streams and the low pressure flow stream in the suction chamber, wherein the low pressure fluid flow stream is entrained by the high pressure fluid flow streams, and wherein each of the series of undulations include an apex that is oriented towards the central axis of the outlet of the nozzle chamber, and the undulations are generally axisymmetric with respect to the central axis.
