“…It was demonstrated that air temperature, radiation, and humidity have a significant relation with the evaporation rate. Bozkurt 9 investigated the effect of different PCMs placed on the walls of the solar pond on the heat storage performance of the system. The increase in the heat storage rate of the pond using PCM was calculated numerically and compared with the pond without PCM.…”

In this work, the effect of with and without phase change materials for long‐term heat storage of a salt gradient solar pond was investigated both experimentally and numerically. Some phase change materials, whose thermal values are close to the operating temperature of the solar pond were selected and examined from fatty acids (camphene, decanoic acid, and palmitic acids) and paraffin derivatives (paraffin wax, C20‐C33, and C16‐C28). A series of experimental studies were then performed with phase change temperature, latent heat and thermal stability, a differential scanning calorimetry, and a thermogravimetric analyzer for sheath, decanoic acid, and palmitic acid. The temperature and enthalpy curve of each phase change material was calculated by months and compared to the solar pond and the longest‐term heat storage was determined. Study shows that the maximum efficiency of the solar pond can be achieved with 24.58% Camphene in November and 22.57% Paraffin C20‐C33 in December. Thus, the camphene shows the best longest‐term heat storage performance thanks to its high melting temperature and density and latent fusion heat. It is one of the best suitable options to improve the heat storage performance of solar ponds.

“…Bozkurt investigated the effect of PCMs on improving the insulation of the pond. He determined that using the PCM allowed heat energy to be stored in the SGSP for a longer time [10]. Ihsan et al investigated the impact of a PCM on the efficiency and applicability of a SGSP, ultimately showing that the use of PCM allows to stabilize the LCZ temperature by the latent heat, thus enhancing the SGSP's efficiency during the colder seasons [11].…”

Faced with the world's environmental and energy-related challenges, researchers are turning to innovative, sustainable and intelligent solutions to produce, store, and distribute energy. This work explores the trend of using a smart sensor to monitor the stability and efficiency of a salt-gradient solar pond. Several studies have been conducted to improve the thermal efficiency of salt-gradient solar ponds by introducing other materials. This study investigates the thermal and salinity behaviors of a pilot of smart salt-gradient solar ponds with (SGSP) and without (SGSPP) paraffin wax (PW) as a phase-change material (PCM). Temperature and salinity were measured experimentally using a smart sensor, with the measurements being used to investigate the stabilizing effects of placing the PCM in the solar pond's lower convective zone. The experimental results show that the pond with the PCM (SGSPP) achieved greater thermal and salinity stability, with there being a lesser temperature and salinity gradient between the different layers when compared to a solar pond without the PCM (SGSP). The use of the PCM, therefore, helped control the maximum and minimum temperature of the pond's storage zone. The UCZ has been found to operate approximately 4 degrees above the average ambient temperature of the day in the SGSPP and 7 degrees in SGSP. Moreover, an unstable situation is generated after 5 days from starting the operation and at 1.9 m from the bottom, and certain points have the tendency to be neutral from the upper depths in 1, 3 m of the bottom.
