Summary
Phase Change Materials (PCMs) have emerged as one of the most promising technologies for thermal energy storage and thermal management applications. Their ability to store and release large amounts of latent heat within a narrow temperature range makes them attractive for numerous applications, including renewable energy systems, electric vehicles, battery thermal management, electronics cooling, smart buildings, industrial waste heat recovery, and aerospace technologies.
Recent advances in material science, nanotechnology, additive manufacturing, artificial intelligence, and digital engineering have led to the development of smart and multifunctional PCMs with enhanced thermal conductivity, improved thermal stability, flame-retardant properties, and integrated sensing capabilities. These innovations are accelerating the transition from conventional thermal storage materials toward intelligent thermal management solutions capable of meeting the requirements of next-generation energy systems.
This Special Issue aims to provide a comprehensive platform for researchers and engineers working on the design, characterization, modeling, optimization, and applications of advanced PCMs. Contributions addressing experimental investigations, numerical simulations, machine learning approaches, digital twins, and industrial implementations are particularly encouraged.
