SIMPLE AND ACCURATE TECHNIQUE FOR SOLVING NONLINEAR EQUATION ARISING OF CONVECTIVE, CONDUCTIVE AND RADIATIVE STRAIGHT FIN VIA COLLOCATION METHOD

In this study, temperature distribution of conductive, convective and radiative straight fins with temperature dependent thermal conductivity is solved by using Collocation Method (CM). The concept of Collocation method is briefly introduced, and then it is employed to derive solution of nonlinear governing equation of fin with a highly nonlinear term because of existing radiation in this study. The obtained result from Collocation Method is compared with numerical Boundary Value problem Method (BVP) to verify the accuracy of the proposed methods. The results reveal that the CM is very effective, simple and more accurate techniques
