Summary: Rapid economic growth has caused energy resource shortages in developing countries. Thermal energy storage, particularly ice storage systems, can be used to decrease net energy usage. A combined experimental and numerical study was conducted on a novel ice-on-coil cold storage system. Initial experiments revealed non-uniform ice formation on the coil tube, which posed a challenge. Inserting baffles in the evaporator improved heat transfer rates and ice production but did not eliminate non-uniformity. Using a modified evaporator with four horizontal-placed coils increased ice thickness, especially at the bottom of the coil. Three-dimensional simulations based on the finite volume method were used to model the solidification process and validate the experimental results.

Summary: In this study, the heat storage performance of nano phase change material (nPCM) was investigated. It was found that the addition of different nanoparticles can decrease the duration of melting and solidification processes. The thermal conductivity, density, and heat capacity properties play important roles in the melting process, while thermal conductivity is critical for solidification. Graphene nanoplatelet showed the highest heat transfer coefficient among all the nanoparticles studied. This study provides valuable insights for developing more efficient thermal energy storage systems.

Summary: This paper studies the Magneto hydrodynamics (MHD) mixed convection and entropy analysis by introducing a power law hybrid nanofluid in a wavy elbow-shaped cavity with a quarter circle hot block and a rotating cylinder. The thermal and hydrodynamics behavior of the cavity is investigated by comparing the Nusselt (Nu) numbers. The study shows that the Nu number increases with an increasing power law index, clockwise rotation enhances the heat transfer rate, and increasing the aspect ratio increases the heat transfer rate.

Summary: Frequent power outages in developing countries lead to food spoilage, where ice storage systems can serve as backup cooling sources. Geometrical optimization of parameters such as helical pitch length can significantly improve the charging rate of ice storage units. The modified Stefan number of refrigerant flow has a considerable impact on the charging rate, while natural convection does not have a noticeable effect on ice formation.

Summary: Incorporating phase change materials (PCMs) in building materials can significantly reduce energy consumption and maintain indoor temperature within comfort zone. This research evaluates the impact of incorporating three different PCMs from the Rubitherm (R) RT line (RT15, RT18, and RT22) in two widely used hollow brick types in Iran for keeping indoor environment warm in cold climate. Various configurations of PCMs are examined, including their melting temperatures in line with or against the thermal stratification of the bricks. The findings show that certain PCM-filled bricks can provide lower heat fluxes compared to hollow bricks for extended periods of time.
