On code verification of 2D transient heat conduction in composite wall

Abstract

The objective of the present research paper is to verify and validate the C++ code to solve a 2D transient heat conduction problem. A 2-D wall comprised of four different materials was chosen as a domain to analyse numerically in a commercial software FLUENT and C++. The results were compared and found that the non-uniformity in conductivity arises when there exists non-homogeneity in the material. It is also found that C++ results varies on 'f' value in finite volume method's (FCM's) discretization scheme which determines the solution scheme as explicit or implicit. The code was executed for explicit and implicit scheme and made sure that it follows Courant-Friedrichs-Lewy (CFL) conditions.
