Summary
Applications of advanced functional nanomaterials and phase change materials improve the efficiencies of the energy storage system, thermal insulation system, and microelectronic system. Phase change materials (PCMs) have been used for thermal energy storage and performance enhancement in different renewable energy systems. Nanotechnology contributes to the performance improvement of energy systems such as solar collectors, fuel cells, and microelectronic systems. The heat transfer performance of PCMs is significantly improved by dispersing high-conductivity materials with nano-dimensions. The enhancement in the melting process of nano-PCMs depends on many factors, such as types of nano-sized particles, nanoparticle concentration, and operating conditions (Rayleigh and Darcy numbers). For the nanomaterials, the melting and solidification processes are accelerated due to the increase in thermal conductivity and the reduction in latent heat of fusion. It is necessary for an in-depth understanding to investigate the influencing mechanism of nanostructures, nanocomposites, and phase change materials on heat transfer and energy storage. The latest scientific findings and R&D trends in energy utilization will be obtained based on the cooperation of researchers from different backgrounds.
