Application of the Haar Wavelet Method on a Continuously Moving Convective-Radiative Fin with Variable Thermal Conductivity

In this paper, we numerically investigate the heat transfer in a continuously moving convective-radiative fin with variable thermal conductivity by using Haar wavelets. Heat is dissipated to the environment simultaneously through convection and radiation. The effect of various significant parameters-in particular the thermal conductivity parameter a, convection-sink temperature theta(a), radiation-sink temperature theta(s), convection-radiation parameter N-c, radiation-conduction parameter N-r, and Peclet number Pe-on the temperature profile of the fin are discussed and interpreted physically through illustrative graphs. Computational results obtained by the present method are in good agreement with the standard numerical solutions. (C) 2013 Wiley Periodicals, Inc.
