Abstract:

This paper gives a review on enhancement of heat transfer over a flat surface equipped with rectangular perforated fins in staggered arrangement in a rectangular tunnel. The range of Reynolds number is fixed and about 13,500– 42,000.Heat transfer enhanced in fin array by porous fins. Experiments were conducted to analyze the natural convection heat transfer of solid and perforated fin array .This paper is result of experimental study to compare the rate of heat transfer with solid and porous fins . .For the analysis of natural convection heat transfer solid and permeable fin blocks are kept inside an isolated chamber .The variation of steady state temperature of base and tip ,the natural convection heat transfer was compared through each of these blocks .The steady state temperatures were noted at constant heat flux .Steady state temperature were recorded at the same time for different angle of inclination . Fin cylinder block having permeable and solid fin were tested for different inputs ( 15W ,30W , 45W ,60W, 75W ) It was seen that permeable fin block average heat transfer rate improved by about 5.63% and average heat transfer coefficient about 42.3% as compared to solid fins with reduction of coast of the material 30%.
