Abstract

Environmental regulations, fluctuating energy prices, and uncertainties in the international energy markets motivate consumers to ensure their security of energy supply. One method to achieve this goal is to use heat storage equipment, which is scalable and applicable in both industrial and residential environments. The present study focuses on latent heat energy storage utilizing paraffin as a phase-changing material. A cube-shaped heat storage test device was investigated both experimentally and numerically. We used the obtained experimental data to validate our effective numerical modeling approach based on the enthalpy method. We proposed an effective numerical approach to take into account the material nonlinearities and the effect of convective flow phenomena on heat transfer processes, while neglecting the exact flow field and spatial distributions.
