Corrected length of fin
WebThe corrected length approximation gives very good results when the variation of temperature near the fin tip is small (which is the case when mL $ 1) and the heat transfer coefficient at the fin tip is about the same as that at the lateral surface of the fin. Therefore, fins subjected to convection at their tips can be treated as fins with ... WebFor the cooling enhancement, the fins (thickness of 1 mm, width of 100 mm, corrected length of 10 mm and fin effectiveness of 16) will be attached on the outer surface. Determine the heat transfer rate for a single fin and the fin efficiency if the fin base temperature is Tb = 105 °C, the ambient fluid temperature is T = 30 °C and the heat ...
