20.500.12556/RUL-125684 Development of CFD-based procedure for 3d gear pump analysis Tumbling Multi-Chamber (TMC) gear pump is a generally unknown type of hydraulic device, which features a unique three-dimensional shape of the gears. The main benefits of such design over the conventional gear pumps are self-adapting tightness of the pump parts, the possibility to mold the parts from a polymer material and high volumetric efficiency, considering the simplicity of the design. The specific working principle of TMC pumps requires a slightly different approach to the numeric modeling and analysis process compared to the conventional gear pump types (e.g. external gear and gerotor pumps). One of the main contributions of the work is the development of an analysis procedure, which allows studying flow and pressure conditions in the TMC pump. This includes the influence of the positioning of the pump parts on spatial and temporal variations in sealing regions and the influence of pressure field propagation in relation to the valve plate position. volumetric pump computation fluid dynamics volumetric efficiency tumbling multi-chamber gear pump CFD volumetric experimental volumetrična črpalka numerično modeliranje tekočin volumetrični izkoristek zobniške črpalke volumetrično eksperimentalno true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-01 20:25:52 2021-04-01 20:25:55 2022-09-05 03:52:03 0000-00-00 00:00:00 2020 0 0 Str. 1023-1034 iss. 1 Vol. 14 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.876.5:621.6(045) 1994-2060 10.1080/19942060.2020.1789506 27653635 RAZ_Munih_Jernej_2020.pdf RAZ_Munih_Jernej_2020.pdf 1 31E0247E4D2ECBBDCDEDD9BCF745A74D 9813c792a8ec309c7c2524aa624e610b5faa5a7d21b6a1f0c980627e5557269c c489c48d-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141525 https://www.tandfonline.com/doi/full/10.1080/19942060.2020.1789506 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141524 Fakulteta za strojništvo 0 0 0
