Charging and discharging processes of low capacity nano-PCM based cool thermal energy storage system: An experimental study

A. Sathishkumar et al.

Summary: The present study investigates the performance of a low-capacity energy storage tank filled with spherical capsules containing nano-enhanced phase change material (nano-PCM) under different heat transfer fluid (HTF) conditions. The study analyzes the influence of HTF inlet temperature and volumetric flow rates on the charging and discharging time of the energy storage tank. It also examines the reduction in charging and discharging time and the amount of latent heat energy stored. The study finds that the dispersion of functionalized graphene nano-platelets (f-GNP) reduces the specific energy consumption of the nano-PCM. Controlling the flow rate of HTF and its inlet temperature can achieve the desired output temperature and average melting rate in practical applications.

Numerical investigation of nano-enhanced phase change material melting in the 3D annular tube with spiral fins

Juan Duan et al.

Summary: In the annular tube with spiral fins, adding nanoparticles to phase change material (nano-PCM) can greatly enhance energy storage efficiency. The study investigates the energy storage process and enhancement rate of nano-PCM in the annular tube with spiral fins, and finds that adding graphene to PCM leads to a sixfold increase in melting rate compared to adding Al2O3. Adding 1% graphene significantly enhances the energy storage process.
