| Abstract: | Based on CFD simulation technology,the heat transfer and flow resistance characteristics of perforated fin were investigated by taking account of various perforation factors,especially the effect of different perforation factor was analyzed.The results show that the flow resistance of perforated fin increases as the perforation rate increases with ignorable change in heat transfer.With reducing of perforation diameter,the heat transfer and flow resistance of perforated fin increases.The heat transfer and flow resistance of the perforated fin with staggered array is greater than the perforated fin with in-line arrangement.The perforation shape is found to have little influence on heat transfer of perforated fin.When the flow is in the laminar regime,the flow resistance of perforated fin with square shape perforation is greater than the perforated fin with round and triangular shape. |
