vorticity equation


vorticity equation

[vȯr′tis·əd·ē i‚kwā·zhən] (fluid mechanics) An equation of fluid mechanics describing horizontal circulation in the motion of particles around a vertical axis: (d / dt) (S + f) = - (S + f) divh c, where (S + f) is the absolute vorticity (S is the relative vorticity and f is the Coriolis parameter) and divh c is the horizontal divergence of the fluid velocity.
