摘要
Heat exchangers are the most crucial device used in many processes & chemical industries, power plants, and critical areas in engineering applications like refrigeration and air conditioning systems. Passive enhancement strategies entail changing the shape of inserts in an existing device to allow heat to transfer from the surface to the fluid without additional power. The passive approach by the different investigations to enhance the heat transfer, reducing the shape and cost of the equipment yield promising results. The effect of Vortex Generators (VGs) on heat transfer enhancement in heat exchangers has been investigated by many investigators by varying geometrical parameters like shape, location, attack angle, aspect ratio, and Reynolds number (Re). In this review paper, significant results and trends of the investigations on Vortex Generators (VGs) have been discussed to further enhancements of heat transfer in the heat exchanger by using passive techniques.
