WebMathematically, the vorticity of a given velocity field, is defined to be the curl of the velocity field, and is usually denoted with the greek letter omega, where we have used the conventional nabla symbol for the gradient: In component form the vorticity is found by expanding the determinant above, Another important aspect of fluid dynamics ... WebApr 25, 2012 · A dynamic equation for the rate of change of the vorticity of a parcel, obtained by taking the curl of the vector equation of motion. The vorticity equation takes on slightly different forms depending on whether height or pressure is taken as the vertical coordinate. With height as the vertical coordinate, and with friction terms omitted, the ...
