Experimental study on enhancing convective heat transfer at outer asymmetrical finned tubes
摘要
Abstract
A new kind of asymmetrical finned tube heat exchanger was designed.The heat transfer process and effect of the asymmetrical finned tube were experimentally studied under four working conditions.Mo-reover,its heat transfer performance was compared with that of the ring-fin tube and smooth tube,through the heat transfer coefficient calculation.The results show that,this asymmetrical finned tube does stronger disturbance to the flow than the ring-fin tube and smooth tube,it has better heat transfer effect than the other two tubes,and with the same heating surface area,it is more compact than the ring-fin tube.关键词
