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 Nc, radiation-conduction parameter Nr, and Peclet number Pe on the temperature profile of the fin, is discussed and physical interpreted through illustrative graphs. doi:10.14456/WJST.2014.40
