|
The present paper reports an experimental study to investigate the heat transfer enhancement over rectangular fin arrays with and without circular perforation of 5mm and 7mm diameter by forced convection. The temperature drop for fin with perforation is more compared to fin without perforation for same heat input of 12.50W and for 03 different velocities. The cross sectional area of the rectangular duct was 210 mm x 230 mm. The data used in performance analysis were obtained experimentally for fin arrays of material aluminum, by varying size of perforation as well as by varying Reynolds number from 7.7×104 to 21×104. It is observed that the Reynolds number and size of perforation have a larger impact on heat transfer coefficient and Nusselt number for both fin with perforation and fin without perforation. |
