Research ArticleOpen accessPhrase in the titleStudies on the Influence of Various Blade Outlet Angles in a Centrifugal Pump when Handling Viscous FluidsM.H.S. Fard, F.A. BoyaghchiIn this study the centrifugal pump performances with different blade outlet angles are tested when handling water and viscous oils as Newtonian fluids. Also, this study shows a numerical simulation of the three-dimensional fluid flows inside the centrifugal pump with different blade outlet angles. For these numerical simulations the SIMPLEC algorithm is used for solving governing equations of incompressible viscous/turbulent … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,706 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleThe Operational Features of Pumping Stations Equiped with Parallel-Connected Centrifugal Pumps for Land-ReclamationKhalid S. Al-RababaThe required water supply of a pump could be provided by means of different combinations of pressure piping and pumping units at different operational costs. The basic indices describing the operational modes for the individual and group pumping units, including the values of the efficiency, are computed. The adequacy of the calculational results that based on the developed mathematical models … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,802 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsStudy of Properties of a Dispersant Used for Extracting Oil with High Gas-Oil RatioVladimir Verbitsky, Aleksey Dengaev, Oleg Zubkov, Dmitry KoshkinThe article presents the bench test results for a dispersant manufactured by Izhnefteplast Company, which specializes in batch production of unique submersible pumping equipment for oil extraction. The submersible equipment is unique in that the working elements of the pumping equipment are made of polymeric materials unlike the conventional concept of pumping machinery for oil production. The relevance of the … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 24 Feb 2016 · 7,293 accessesView PDF Cite

The conclusion states the need in carrying out such tests before the start of biological experiments involving animals. An example of the device developed at Central Research Institute of Robotics and Cybernetics-a centrifugal … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 11 Feb 2016 · 7,250 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling and Performance Analysis of a Petroleum-Pipeline-Pressure-Boosting Station Powered by Two-Shaft GT EngineYousef S. H. Najjar, Mohammad Z. M. Yousef, Aad M. A. Al-MahgariThis study offers modeling and performance analysis of a pressure-boosting station for petroleum pipelines using a sustainable two-shaft GT engine to drive a three-stage centrifugal pump. The modeling is divided into three steps; matching the GT engine components at the maximum efficiency line, matching the pump performance with the requirements of the pipeline system to generate the pump load curve, … …Energy Research Journal, Vol. 12, Issue 1 · 18 Jan 2022 · 10,510 accessesView PDF Cite
