Numerical computation of metal oxidation problems on bounded domains Academic Article uri icon

abstract

  • This paper is a study of metal oxidation problems with moving oxidation fronts, modeled by Fickian oxygen diffusion through the oxide scale and metal. A numerical algorithm is developed and implemented based on a variable grid finite difference scheme. A domain transformation technique is introduced for the space and time variables, resulting in a transformed problem defined over a fixed domain but with non-linear diffusion equations. The numerical algorithm is implemented for nominal values of the material constants corresponding to titanium alloys at elevated temperatures. Three different benchmark problems with planar, cylindrical and spherical oxidation fronts are analyzed in this work. Also, the influence of the geometry of bounded domains on moving oxidation fronts is discussed. © 1998 Elsevier Science Ltd. All rights reserved.
