Heat transfer rates were measured to a commercial paraffin wax undergoing freezing and melting in vertical cylindrical containers. Circular, square and axially‐partitioned cylinders were used. Natural convective motions were followed using tracer particles in a visual study of melting. Freezing fluxes were well predicted by a quasi‐steady conduction model. Melting fluxes were enhanced by natural convection. A melting model employing an effective thermal conductivity predicted melting fluxes satisfactorily.
