| Abstract: | The pattern of finned array affects the heat transfer performance of a heat exchanger.The heat transfer coefficient of tube and shell heat exchanger with and without a finned array is investigated by computational fluid dynamics.The results reveal that the heat transfer coefficient of shell and tube heat exchanger with in-line-fin and staggered-fin increases by 87.8% and 98.2% of that without finned array,respectively,and with 35.1%and 37.6% increments of pressure drop correspondingly.The heat transfer coefficient of heat exchanger with staggered-fin is increased to 5.2% compared with that with in-line-fin array. |
