ABSTRACT:
A method of and apparatus for momentum exchange of a pressurized fluid including a jet nozzle for discharging a jet of pressurized fluid produced by a pressure pump, a first inlet opening provided downstream of the jet nozzle, an air layer generating pipe, and a momentum exchange tube disposed downstream of the air layer generating pipe. A layer of air, around a highly pressurized fluid released from the jet nozzle, is formed by the air layer generating pipe. The momentum exchange tube is formed of a substantially straight construction and has an inner diameter which is greater than an inner diameter of the air layer generating pipe. An outlet provided at the momentum exchange tube for using, as a lifting elevation, the pressure produced by urging the pressurized fluid against air in the momentum exchange tube. The lifting force is calculated through dividing the pressure of the pressurized fluid by a ratio of the inner diameter of the momentum exchange tube and the diameter of the jet nozzle aperture, and multiplying the resultant value by an inertial force of the pressurized fluid.
