Circulation in fluid mechanics
Web• Circulation, which is a scalar integral quantity, is a macroscopic measure of rotation for a finite area of the fluid. • Vorticity, however, is a vector field that gives a microscopic measure of the rotation at any point in the fluid. … WebIn fluid mechanics, Kelvin's circulation theorem (named after William Thomson, 1st Baron Kelvin who published it in 1869) states: [1] [2] In a barotropic, ideal fluid with …

WebCirculation Circulation is another measure of fluid rotation. If we consider a closed path C around the fluid flow then circulation is defined as the line integral of the tangential velocity around C. By applying the Stoke’s theorem, circulation can be related to the vorticity as Notice that vorticity is a vector quantity and gives the measure of local rotation while … 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 ...

In physics, circulation is the line integral of a vector field around a closed curve. In fluid dynamics, the field is the fluid velocity field. In electrodynamics, it can be the electric or the magnetic field. Circulation was first used independently by Frederick Lanchester, Martin Kutta and Nikolay Zhukovsky. It is usually denoted Γ (Greek uppercase gamma).
