Résumé

This investigation treats analytically heat transfer in circular fins composed of two materials considering radial and transverse temperature variations. The two-dimension Laplace equation is solved by separation of variables and results obtained are compared with those for a single material fin with radial temperature variations only. The one-dimension analysis employs a volumetric average thermal conductivity to approximate the two-material fin. Significant errors in the composite fin heat transfer are found due to neglect of the transverse temperature gradients.
