Abstract EN
Explicit analytical expressions for the temperature profile, fin efficiency, and heat flux in a longitudinal fin are derived.
Here, thermal conductivity and heat transfer coefficient depend on the temperature.
The differential transform method (DTM) is employed to construct the analytical (series) solutions.
Thermal conductivity is considered to be given by the power law in one case and by the linear function of temperature in the other, whereas heat transfer coefficient is only given by the power law.
The analytical solutions constructed by the DTM agree very well with the exact solutions even when both the thermal conductivity and the heat transfer coefficient are given by the power law.
The analytical solutions are obtained for the problems which cannot be solved exactly.
The effects of some physical parameters such as the thermogeometric fin parameter and thermal conductivity gradient on temperature distribution are illustrated and explained.
