Abstract: Disclosed are devices and methods for generating electrical power by using airflow energy to create air pressure fluctuations within Helmholtz chambers containing piezoelectric materials. The generator device includes an intake having stationary blades for directing wind into a flow treatment stage, which in turn directs a flow of modified air into a flow interface stage. In the flow interface stage, a plurality of Helmholtz chambers containing piezoelectric units are configured around a flow interface chamber wherein passing modified airflow establishes air pressure fluctuations within the Helmholtz chambers thereby causing the piezoelectric units to generate electricity. The device routes generated electrical current to a processor for use as a power source. Also disclosed is a method of generating electrical power using airflow energy. The method includes collecting airflow from the environment to create pressure fluctuations within containers housing piezoelectric units.

Abstract: A gas-oil separation plant (GOSP) is configured to process crude oil produced from a well. A production stream from the well operates at a first pressure. A processed crude oil stream from the GOSP flows to a multi-phase ejector. The multi-phase ejector induces flow of a production stream from the well in response to the flow of the processed crude oil stream.

Abstract: Devices for producing vacuum using the Venturi effect have a housing that defines a suction chamber, a motive passageway converging toward the suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway having a first port in fluid communication with the suction chamber. Within the suction chamber, a motive exit of the motive passageway is spaced apart a distance from a discharge entrance of the discharge passageway to define a Venturi gap. A fletch that has a first hollow body section that terminates at or proximate a motive exit and a second hollow body section that terminates with a fletch entrance in fluid communication with the suction passageway upstream of the first port is present in the motive passageway. During operation, fluid flow through the motive passageway draws fluid flow through the first port into the suction chamber and through the fletch.

Abstract: A tail gas exhausting pressure stabilization control system can control the pressure and the flow rate of a gas and a driving gas inputted therein, such that when the gas and the driving gas are mixed and outputted to a tail gas exhausting outlet, the pressure thereof can be controlled under a predetermined pressure. Besides, when the back pressure is generated because of the exhausted gases from the outlet, an energy-saving module can adjust the pressure of the driving gas outputted to an eductor in accordance with the detecting result of the back pressure in order to resist the back pressure. Thus, the exhausted gases from the outlet can be still under the predetermined pressure between the gas and a gas distribution component so as to stabilize the pressure and flow rate of the exhausted gases from the outlet and save the driving gas.

Abstract: An ejector includes a body including an inflow space into which a refrigerant flows, a passage formation member disposed inside the body and having a conical shape, and a nozzle passage having an annular cross section which functions as a nozzle and a diffuser passage having an annular cross section which functions as a pressure increase portion, the nozzle passage and the diffuser passage being disposed between an inner wall surface of the body and a conical lateral surface of the passage formation member. A drive mechanism that displaces the passage formation member in a direction along a center axis is coupled to an upstream actuating bar which extends from the passage formation member toward the inflow space and is slidably supported by the body. Center axes of the passage formation member, the upstream actuating bar and the inflow space are coaxial with each other.

Abstract: A Venturi type ejector having a feed duct for feeding fluid under pressure with the duct extending along a central axis. A first expansion chamber is connected to the feed duct; a first mixing chamber is connected to the expansion chamber; a first suction chamber is connected to the mixing chamber; and an exhaust chamber is connected to the first mixing chamber. The ejector where the fluid under pressure penetrates into the first expansion chamber along a plurality of directions extends in a plane that is substantially orthogonal to the central axis. A vacuum generator includes such an ejector.
