Thermally Asymmetric Triangular Fin Analysis

초록

The nondimensional heat loss from a geometrically symmetric, but thermally asymmetric, triangular fin is investigated as a function of the nondimensional fin length and a ratio of upper and lower surface Biot numbers (Bi2/Bi1) using the two-dimensional separation of variables method. The comparison between the nondimensional temperature for the thermally asymmetric condition and that for the thermally symmetric condition is made. The relationship between the nondimensional fin length and the ratio Bi2/Bi1 for equal amounts of heat loss is also discussed, as well as the relationship between Bi2/Bi1 and Bi1 for equal amounts of heat loss.
