Patent number: 10218247Abstract: An electric pump powered by an electric motor having a stator disposed within a hollow rotor is provided. Impellers on the rotor outer surface extend into a fluid flow path defined by the pump. One or more torque-producing rotor sections are driven by a plurality of independently controllable stator sections disposed within the rotor cavity. The relative positions of the rotor and stator are maintained by a plurality of bearings configured to allow rotation of the rotor and defining a bearing span. The pump is configured such that the stator and rotor share the same bearing span. Such an arrangement reduces motor windage losses relative to conventional motors in which the rotor is disposed within the stator, owing to a reduction in the diameter of the air gap between the stator and the rotor. In addition, the peripheral speed of the pump is increased owing to an increase in the rotor diameter.Type: GrantFiled: June 3, 2015Date of Patent: February 26, 2019Assignee: General Electric CompanyInventors: Vittorio Michelassi, Siddharth Navinchandra Ashar, Ismail Hakki Sezal, Rene du Cauze de Nazelle, Egidio Marotta, Ravishankar Balasubramanian, Mohamed Osama

Patent number: 9816965Abstract: A method of detecting a vibration node between a non-collocated sensor-actuator pair of a rotatable component includes applying an excitation signal to an actuator of the sensor actuator pair. The method also includes obtaining frequency response data from the sensor-actuator pair. The method further includes analyzing the frequency response data to ascertain a resonant frequency of the rotatable component. The method includes identifying a resonance/anti-resonance peak pair in the frequency response data for the non-collocated sensor-actuator pair. Furthermore, the method includes determining whether the vibration node is located between a sensor and the actuator of the non-collocated sensor-actuator pair based on the resonance/anti-resonance peak pair.Type: GrantFiled: November 14, 2014Date of Patent: November 14, 2017Assignee: General Electric CompanyInventors: Rosa Castane Selga, Siddharth Navinchandra Ashar, Christoph Boeld, Mohamed Osama, Adolfo Anta Martinez

Publication number: 20170254828Abstract: A flow angle probe is provided having (a) a probe flap for contacting a moving fluid within a fluid conduit; (b) a probe body mechanically coupled to the probe flap; (c) a force sensor disposed within the probe body and operationally coupled to the probe flap; and optionally (d) a probe shaft coupled to the probe body. A deflection of the probe flap caused by contact with the moving fluid produces a corresponding force sensor signal output which is minimized by rotation of the probe flap. The angle between this point of minimum deflection and a reference position is taken to be the flow angle of the moving fluid in the vicinity of the probe flap. The novel flow angle probes disclosed herein may be used in a wide variety of turbomachines and fluid processing systems, and applications, including turbomachine design and operational control, and in flow assurance.Type: ApplicationFiled: March 21, 2016Publication date: September 7, 2017Inventors: Andreas Herrig, Carsten Michael Schneider, Erik Mele, Siddharth Navinchandra Ashar

Patent number: 9512700Abstract: A subsea fluid processing system is provided containing a liquid reservoir, an inlet tank, a pump, an outlet system, and a fluid re-circulation loop. The liquid reservoir circulates a primer liquid stream to the inlet tank via the fluid re-circulation loop. The inlet tank further receives a first production fluid stream and mixes it with the primer liquid stream to produce thereby a second production fluid stream having a reduced gas volume fraction (GVF) relative to the first production fluid stream. The pump receives the second production fluid stream from the inlet tank and increases its pressure. Further, the outlet system containing the liquid reservoir receives the second production fluid stream from the pump and separates at least a portion of the primer liquid stream from a principal production stream. The primer liquid includes at least one exogenous liquid not derived from the first production fluid stream.Type: GrantFiled: December 12, 2014Date of Patent: December 6, 2016Assignee: General Electric CompanyInventors: Guillaume Becquin, Siddharth Navinchandra Ashar, Jr., Vittorio Michelassi, Rosa Castane Selga, Rene Du Cauze De Nazelle
