Prediction of Fin Performance under Natural Convection using Finite Element Method
Mary Pasam , K Chandra Sekhar
This study examines the heat transfer enhancement from a vertical rectangular fin embedded with circular perforations under natural convection compared to the equivalent solid (non-perforated) fin. The parameters considered are geometrical dimensions and thermal properties of the fin and that of the perforations. The study considered the heat transfer coefficients of vertical plates due to number of perforations in the natural convection. The experimental setup of the literature is used for comparison. The same experimental setup is simulated with the help of ANSYS. The heat transfer through rectangular fins with different number of circular perforations in rectangular pitch is compared with experimental results of the literature, non-perforated (solid fin) fin of same dimension and of triangular pitch circular perforated plate and also compared with circular and triangular combination of perforations and circular perforation with increase in diameter. In the study it is found that ANSYS metal temperatures are matched with experimental thermocouple results within ±10%. Also, non-perforated plate shows significantly higher temperatures. Change of perforation type with equivalent cross sectional area or pitch of perforation doesn’t change the metal temperatures much. But increase in perforation diameter resulted in reduced metal temperatures compared to all other variations & is one of the best idea to implement for the better heat removal.
