### A Haar Wavelet Study on Convective-Radiative Fin under Continuous Motion with Temperature-Dependent Thermal Conductivity

#### Abstract

In this paper, the Haar wavelet method is applied to find an approximate solution for heat transfer in moving fins with temperature-dependent thermal conductivity losing heat through both convection and radiation to the surroundings. The effects of various significant parameters involved in the problem, such as the thermal conductivity parameter *a*, sink temperature , convection-radiation parameter *N _{c}*, radiation-conduction parameter

*N*, and Peclet number

_{r}*Pe*on the temperature profile of the fin, is discussed and physical interpreted through illustrative graphs.
