Abstract—The reusing process of wind turbine blades demands machining operations, commonly performed with laser tools due to the inherently anisotropic nature of the fiber reinforced polymer (FRP). Therefore, it is essential to understand the heat transfer in anisotropic media to control the heat-affected zone (HAZ), established when the blade is cutted. This work aims to use the Multi-Point Flux Approximation (MPFA) method in the numerical solution of transient heat conduction problems in anisotropic media. This poses as an alternative to the traditional Two-Point Flux Approximation method (TPFA), which has a wide range of applications however fails to generate accurate solutions to problems with certain anisotropic materials configurations. Notwithstanding that the MPFA method is well-known, the transient version developed here is still unexplored in literature. The results observed with classical benchmark problems show that MPFA can describe the solutions of transient anisotropic problems more accuratelly than the traditional TPFA.

Index Terms—Anisotropic media, heat transfer, reuse, wind turbine blade.
