| Abstract: | In this article, the SIMPLE algorithm for collocated-grids in body-fitted coordinate system is adopted to predict the air-side performance of dimpled fin surfaces. The fluid flow and heat transfer characteristics of the fin surface with three-row staggered arrangement dimples were studied in different inlet velocity. In order to comparing the performances of dimpled fin surfaces in different dimpled height and print axis length, numerical simulations are conducted at inlet velocity of 2 m/s. |
