Does anyone know about the effect of horseshoe vortex on heat transfer?
In general
The term horseshoe vortex is also used in wind engineering to describe the flow pattern created by strong winds around the base of a tall building. This effect is amplified by the presence of a low-rise building just upwind. This effect was studied at the UK Building Research Establishment between 1963 and 1973 and the cause of the effect is described in contemporary wind engineering text books.
In hydrodynamics, a form of horseshoe vortex forms around bluff bodies in the flowing water, for instance around bridge piers. They can cause scouring of bed materials from both upstream and downstream of the pier.
In nature, a horseshoe vortex can cause a horseshoe cloud to form.There are some Notes may help

Thank you very much Ahmed Abdelhameed
It is very valuable for me....
horseshoe vortex is the name used to identify the vortex created in front of tubes in the channels between two consecutive fins of a heat exchanger. the flow facing the frontal part of tubes change its path and impinging on the fins. As results two vortex are created at both sides of the tube flowing in the same direction of the main flow. that vortex are responsible for the heat transfer enhancement in the area where they are flowing and its intensity is increasing with velocity of the main flow.
Does anyone have some recent literature on the effects of HV on the heat transfer rate?
