A note on the decay of vortices in a viscous fluid

WebThe decay of vortices in flows of an electrically conducting fluid in the presence of a magnetic field is studied. Two flow configurations are considered: 1) flow in a double array of vortices; 2) flow behind a two-dimensional grid. It is found that in the presence of a uniform transverse magnetic field, the vortices decay much faster than those in a … raymond boucherWebIn fluid dynamics, a vortex (PL: vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved.

WebThe evolution of a viscous vortex pair is investigated through the use of a heuristic model. The model is based on the linear superposition of two Oseen vortices of opposite circulation spaced a distance 2b apart. The vortices are allowed to evolve through viscous diffusion and their mutual induction. The motion is unforced and as a consequence the total … Web13 de abr. de 2024 · Bluff bodies are prone to vortex-induced vibration (VIV), a phenomenon that causes these structures to obey a cyclic motion, both in the direction of the incoming flow and (more intensely) in the transverse direction (Williamson and Govardhan, 2004 55.Williamson, C.
