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 LVGin heat transfer enhancement is better than others during simplex pins tests.Furthermore
the mixed configuration of columned turbulent pins and LVGhas the best performance in natural convection heat transfer enhancement
