Circulation in fluid mechanics
WebMar 29, 2006 · A realistic theoretical model of steady Langmuir circulations is constructed. Vorticity in the wind direction is generated by the Stokes drift of the gravity-wave field acting upon spanwise vorticity deriving from the wind-driven current. We believe that the steady Langmuir circulations represent a balance between this generating mechanism and ... http://ecoursesonline.iasri.res.in/mod/page/view.php?id=1076#:~:text=Circulation%20is%20the%20total%20%E2%80%9Cpush%E2%80%9D%20you%20get%20when,vector%20that%20is%20locally%20tangent%20to%20the%20contour.

WebThe distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterise vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance from the axis. WebThis book addresses the problem of inferring the state of the ocean circulation, understanding it dynamically, and even forecasting it through a quantitative combination of theory and observation. It focuses on so-called inverse methods and related methods of statistical inference. ... Journal of Fluid Mechanics is the leading international ...
