Summary: Phase change materials (PCMs) are preferred for latent heat storage due to their high energy storage densities and low energy losses. The low thermal conductivity coefficients of PCMs hinder their commercialization and broader applications. Double-pipe energy storage (DPTES) with PCM is suitable for cases where there is a mismatch between the generation and consumption times of thermal energy from sources like solar energy. This study investigates the effects of different inner and outer channel combinations on melting and solidification performance.

Summary: This study investigates the impact of fin type and orientation on the charging and discharging processes of a horizontal concentric filled with phase change material. The results show that the performance is significantly improved with the use of transversal corrugated fin design. The melting process is mainly influenced by natural convection, while conduction is the main mode of heat transfer in the solidification process. The transversal corrugated fin design outperforms other cases in terms of melting time reduction, and the overall processing time is significantly shorter.

Summary: The effects of pipe orientation angle on the performance of latent heat thermal energy storage systems were investigated. It was found that increasing the orientation angle of the pipe can reduce the melt fraction and increase the melting time and absorbed heat flux. However, the orientation angle has no impact on the solid fraction during solidification.

Summary: This study proposes a solution with hybrid fins and nanoparticles to address the nonuniform melting issue of PCM in the widely used vertical shell-tube storage unit, which significantly affects the thermal performance. By using half-fins and full-fins, nanoparticles are dispersed uniformly and non-uniformly in different regions of the storage unit. Numerical analysis reveals that using full-fins reduces heat runoff in the bottom region and increasing nanoparticles concentration enhances heat conduction. An optimized nanoparticles concentration of 3.5-2.0-6.5 vol% reduces melting time by 29.8% and improves melting rate uniformity by 94.0%.
