In the past twenty years, the behavior of the apparent thermal conductance of two or three phase systems comprised of solid particles with nanometer dimensions suspended in fluids, dubbed nanofluids, has been greatly contested in literature. After the study of the seven simplest nanofluids, Cu, CuO, Al2O3, and TiO2 suspended in water and ethylene glycol, ...
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 ...
