Computational Solution of the Direct Heat Transfer Problem in Laminated Composites Using the Finite Volume Method.

Resumo

Laminated composite materials are widely used in engineering applications due to their excellent thermal and mechanical properties. However, internal defects such as delamination at the interfaces between layers can significantly affect their performance and compromise structural integrity. In this context, accurate thermal analysis becomes essential for evaluating the reliability of these materials and supporting the early detection of failures.
This project proposes the development of a robust numerical model to solve the direct heat transfer problem in laminated composites using the finite volume method (FVM). The study considers transient, two-dimensional heat conduction under different boundary conditions and thermal properties. The governing partial differential equations are discretized using the FVM, and the solution is obtained through an implicit time integration scheme to ensure numerical stability and precision. A computational code is being developed in Python, and its validation will be carried out using benchmark problems or analytical solutions available in the literature.
The model aims to simulate the temperature distribution within laminated composites and analyze how variations in material properties and contact conditions influence heat flow. The results will provide insights into the thermal behavior of these materials, helping to assess their structural integrity. The proposed approach may also serve as a foundation for future studies involving inverse problems, failure detection, and thermal characterization of advanced composite systems.
