Phase change materials (PCMs) are substances that release large amounts of energy in the form of latent heat when they freeze. Paraffin waxes have many of the desired characteristics PCMs exhibit except that they have low thermal conductivity. In this experiment, Alumina and Carbon Black nanoparticles were added to two types of paraffin waxes (melting points of 20-25 °C) to increase their thermal conductivity. A Transient Plane Source (TPS) measured ...
