Abstract

A combined domain and integral techniques to solve planar oxidation problem S.G. Ahmed Department of Eng. Math, and Phys. Faculty of Engineering, Zagazig University, Zagazig, Egypt Abstract In this paper, a semi-analytical method is developed to solve planar oxidation problems in a semi-infinite domain. The proposed method is based mainly on a combined procedure for both domain transformation and boundary layer integral techniques in the oxide layer. A numerical algorithm is then developed to find the unknowns in the assumed profiles for oxygen concentration in both layers. The results of the proposed method were compared with previous available approximate solutions and gave a good agreement. 1 Introduction In some applications of engineering industries, especially where elevated high temperature is a factor, it is recommended special types of metal matrix composites be used. Metal matrix composites have been proposed for this purpose due to their high strength and abil
