Hybrid analytical and finite element simulation of a latent heat storage exchanger: Comparison of heat transfer models for enhanced thermal conductivity phase change material

Résumé

In order to cut down the computing time, a simplified method for heat transfer analysis within a multi-tube and multi-plate latent heat storage exchanger is proposed. This method associates a 2D Finite Element method to solve energy equation within each plate and an analytical model to link the plates between them. Different formulations of the energy equation have been tested and compared with experimental results on a simple configuration. Enthalpy formulation, temperature dependent specific heat method, and source term of crystallization associated to kinetic equation method are the different options studied. The limitations of each methods is then exhibited.
