Experimental study in natural convection heat transfer enhancement

This paper focuses on study of heat transfer enhancement in natural convection along upright board. Comparing the different effects of heat transfer enhancement by using columned turbulent pins, conical turbulent pins, prisms, pyramids, and LVG (longitudinal vortex generator) arrays, the results show that the performance of LVG in heat transfer enhancement is better than others during simplex pins tests. Furthermore, the mixed configuration of columned turbulent pins and LVG has the best performance in natural convection heat transfer enhancement, which enhances heat transfer by 24.5 percent.
