Since vortex stretching is a 3D phenomenon, can 2D model simulate it properly? If not, how its influence is considered in 2D? As we know, the vortex stretching mechanism is related to the energy and momentum transfer. I remember on class the professor told me the vortex stretching can't be simulated in 2D. From the 2D k-epsilon equation the energy is transfered and dissipated, so if vortex stretching is included, which term in the equation accounts for it? Thank you in advance.

nobody help me on this?
