Analysis on the Heat Transfer Performance of Jacketed Tube Heat Exchanger with Different Finned Array

Abstract:

The heat transfer performance of heat exchanger dependents on the pattern of finned array. The heat transfer coefficient of jacketed tube heat exchanger with and without finned array was investigated by computational fluid dynamics. The results reveal that: the heat transfer coefficient of jacketed tube heat exchanger with in-line-fin and staggered-fin increase to the 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 increased to 5.4% compared with that with in-line-fin.
