WebThe vorticity equation describes the evolution of the vorticity of a fluid element as it moves around. In fluid mechanics this equation can be expressed in vector form as follows, where, is the velocity vector, ρ is the density, p is the pressure, is the viscous stress tensor and is the body force term. http://web.mit.edu/13.021/demos/lectures/lecture9.pdf
