| Abstract: | The enthalpy method was employed to investigate the phase change process in a latent thermal energy storage(LTES) system using multiple phase change materials(PCMs).Numerical computations are carried out to analyze the influence of the PCM compositions in multiple PCMs on the heat transfer performance of the LTES system.Numerical results indicate that there is an optimum mass fraction of multiple PCMs for the LTES system to reach the maximum heat transfer rate. |
