1-D Heat Transfer in Multilayer Materials Using a Finite Volume Approach

Abstract

One-dimensional transient heat transfer analysis is frequently used to provide quick estimates of the performance of thermal protection system concepts for reentry systems. While finite difference techniques are commonly employed when solving simple single-material thermal problems, more complex cases with multiple layers can complicate the numerical implementation. A control volume analysis is used in the present work to derive a finite volume approach to the 1-D thermal analysis problem using generalized coordinates. Details of the numerical implementation are also discussed to highlight how this technique can simplify the overall solution process. Finally, two example problems are used to validate the accuracy of the approach, one of which involves analysis of a multilayer TPS problem with non-uniform grid spacing.
