In present study, a novel method is proposed to optimize performance of multi-stage multiphase pump by theoretical prediction based on Oseen vortex. The velocity moment of flow field downstream diffuser can be predicted according to established theoretical model, and it is applied to optimize inlet ...
Kelvin waves and the singular modes of the Lamb-Oseen vortex Columnar vortices are known to support a family of waves initially discovered by Lord Kelvin (1880) in the case of the Rankine vortex model. This paper pre... FABRE,D. - 《Journal of Fluid Mechanics》 被引量: 157发表: 2006年...

Hamel-Oseen vortexNumerical simulationVortexVortex pumpWe did a numerical study of the internal flow field of a vortex pump. Five operating points were considered and validated through a measured characteristic curve. The internal flow pattern of a vortex pump was analyzed and compared to the Hamel...
The displacement pattern arising from the decay of a two-dimensional Lamb-Oseen vortex in a Newtonian fluid can be closely modeled by the closed-form expression presented here. This formula enables Lamb-Oseen vortex simulation orders of magnitude faster than can be accomplished using finite-element ...
Oseen Vortex #1 idk New Member Join Date: Feb 2025 Posts: 1 Rep Power: 0 Hi, I am new to ansys and so don't have much experience with it but have to use it for a project at uni. Can anyone help me on running a 2d simulation on how to place two oseen vortices near the ...
Finally, the design method is applied, and results show that the average efficiency of redesigned pump under the working conditions is 1.04% higher than that of baseline pump, which validates the reliability of proposed design method by theoretical prediction based on Oseen vortex. Analysis on ...
The optimal response in the Lamb-Oseen vortex is studied by considering the harmonically forced problem with frequency 蠅. High variance levels are sustained in these systems under periodic forcing. In the axisymmetric case n=0, the response is the largest when the input frequency is zero. When...
Lamb–Oseen vortexOptimal responsePeriodic forcingThe level of the response energy is compared to that without forcing. Different azimuthal modes are studied and compared. The reason of the location of peaks for helical modes is presented. The non-smoothness of curves for helical modes is explained...
