WebMar 1, 2016 · Finally, Figure 9 shows the fin efficiency as a function of fin parameter m for R b =0.2, 0.4, 0.6, and 0.8. For each geometry, the fin efficiency decreases as m increases as was seen in Figure 8. For a fixed m, the fin delivers higher efficiency as R b increases, that is, as the dimensionless fin height, 1 − R b, decreases. Thus a shorter ...
WebA cylindrical fin of diameter 1 cm and length 5 cm with negligible heat loss from the tip has an effectiveness of 15. If the fin base temperature is 280 °C, the ambient temperature is 20 °C, and convective heat transfer coefficient is 65 W/m²K; what are the rate of heat loss from the fin and fin efficiency? [2+1] 3. WebApr 18, 2024 · A fin serves as an extended surface to enhance the heat transfer from a larger heated mass to which it is attached. We use a multiobjective optimization (MO) approach for a fin in steady-state to analyze the dynamics of effectiveness and efficiency simultaneously.
