In this study, the actual heat transfer coefficient of a phase-change material (PCM) was measured experimentally with the purpose of improving the heat storage rate of an automotive coolant waste heat storage system using the latent heat of the PCM. The heat transfer rate and time required to...

Two titania–water (TiO2–water) nanofluids were prepared by dispersing TiO2 nanoparticles in rod shapes (rutile TiO2) and in spherical shapes (anatase TiO2) into deionized water. The effect of the TiO2 nanoparticles on the crystallization behaviors of the nanofluids were investigated using...

Thermal energy storage (TES) is a technology with a high potential for different thermal applications. It is well known that TES could be the most appropriate way and method to correct the gap between the demand and supply of energy and therefore it has become a very attractive technology. In...

Thermal energy storage using phase change materials (PCMs) have been a focal point in the efficient energy utilisation in buildings for over 30years. The possible use of PCM in buildings is becoming more and more attractive due to the large energy storage density and nearly isothermal nature of...

Palmitic acid (PA) is one of the main phase change materials (PCMs) for medium temperature thermal energy storage systems. In order to stabilize the shape and enhance the thermal conductivity of PA, the effects of adding nitrogen-doped graphene (NDG) as a carbon nanofiller were examined...
