Abstract

The isothermal, periodic and linear melting of encapsulated ice for cold thermal energy storage has been investigated numerically. The traditional enthalpy-porosity method is used to track the motion of the liquid-solid front. A non-Boussinesq approach is considered to take in to account the density inversion inside the water. A detailed parametric investigation is performed for melting in shells of 1, 10 and 100 mm2 in surface. Transient numerical simulations are performed using SIMPLEC algorithm. The computational results show how the transient phase-change process depends on the thermal and geometrical parameters of the system such as the wall temperature the shell surface and the heating rate. Dimensional analysis of the results is performed and presented as the specific heat flux, PCM melt fractions and the variation of the temperature inside the shell.
