He's homotopy perturbation method for the temperature distribution in convective straight fins with temperature-dependent thermal conductivity

Lan Xu

Abstract


This paper applies J. H. He's homotopy perturbation method
(HPM) to calculate the temperature distribution in convective
straight fins with temperature-dependent thermal conductivity. The
temperature distribution of straight fins is obtained as a function
of thermo-geometric fin parameter. Comparison with the exact
solution shows that the method is very effective and convenient,
only one iteration leads to an accurate solution.
