Experimentation carried out as mentioned in this paper predicts the flow of air over the fin array and the heat transfer due to natural convection. Fin array is modeled using Pro/E and material used is aluminum. Nine rectangular fins are used and placed over a heat source. We consider three different heat inputs while keeping all other parameters constant. Experimentation is done for fin array without notches and with notches while keeping the end fins without notches. Notches with square cross section are used for experimentation. Variation in notch cross section is provided by reducing the notch area by 10%, 20% and 30% respectively.
