What are the mechanisms for generation of vorticity

I was wondering about the physical mechanisms for generating vorticity and also their mathematical formulations. I know about viscous diffusion of vorticity and vortex stretching -but there are mainly mechanisms for how vorticity changes right? not its production..any comments would be appreciated

Hi Nik,
I assume that mean shear (at a solid boundary, or at a fluid of different properties) would contribute to generating vortices and such vorticity. I believe that the main mechanism that produces vorticity is the existence of velocity gradients....

maybe this helps!
merrry christmas!

yes that makes sense..thanks for ur reply merry xmass to u too and let me know if u learn more about vorticity generation
