Abstract

Abstract:

The charging process of a latent heat thermal energy storage unit inside a square cavity with a sinusoidal temperature distribution is numerically investigated in this paper by using the lattice Boltzmann method. The effect of the electric field, amplitude, wave number, and phase deviation of the temperature distribution on the melting performance is studied. Based on the numerical results, it is shown that, compared with the case without an electric field, the melting efficiency of the latent heat thermal energy storage is significantly improved, and this phenomenon becomes more pronounced with a stronger electric field. In addition, when the wave number of the temperature distribution is 1.5, the total melting time of the system is the lowest, whereas the influence of amplitude and phase deviation on the melting performance largely depends on the electric Rayleigh number.

Key words: latent heat thermal energy storage, electrohydrodynamic, sinusoidal temperature distribution
