Information × Registration Number 0200U004223, 0197U016595 , R & D reports Title Investigation of the working process of the borehole turbine-pump units with gas-saturated and high-viscous oils. popup.stage_title Head Yevtushenko A.O., Registration Date 07-06-2000 Organization Sumy State University popup.description2 Object of investigation - the working process of the borehole turbine-units. Purpose of investigation - creation of new high-productive technical means for extraction of the gas-saturated and high-viscons oils. The relust obtained are new and consist in the following: the working process theory of an axial-flow pump is completed with the data about the influence of velocity moment before an impeller; the half-empirical theory of the working process of a free-vortex pump is stated as well as the technique of recalculation of its characteristics from water to gas-liquid mixture; the program means for carrying out the calculational experiments on the basis of spacial potential and axisymmetrical viscous liquid flows are claborated; the new elements of the hydraulic parts of hydromachines are elaborated, the small-dimensional centrifugal turbine stages are designed and experimentally tested. The research are incorporated in the Ukraine oil-gas complex. Product Description popup.authors popup.nrat_date 2020-04-03 Close
