Melting convection is a factor that greatly affects the progress of actual melting heat storage, as well as the thermal conductivity of the heat storage material. Generating convection in the molten region of the latent heat storage material significantly reduces the latent heat storage time. However, in latent heat storage, where the phase change from solid to liquid progresses, it is difficult to adopt a mechanical stirring method. Therefore, the heat exchange method adopted in this study is heat transfer in which high-temperature air jets impinge on the latent heat storage material. Therefore, it is possible to generate forced convection in the molten liquid phase during latent heat storage. This paper describes the results of an experimental investigation of the impinging jet melting process of paraffin-based latent heat storage materials.
