To improve the efficiency of PCM-based thermal storage devices, various techniques are being used, such as, use of fins, use of multiple PCMs, use of heat pipes, and enhancing the thermal conductivity by adding nano-particles. In this work, 2D unsteady numerical simulations, using ANSYS-Fluent with the enthalpy-porosity formulation, are performed to study an effect of a uniform transverse magnetic field on heat transfer inside a cavity filled initially with a solid gallium. The horizontal walls of the cavity are considered insulated and vertical walls are, respectively, considered hot and cold. The magnetic field is characterized by the Hartmann number (Ha) and the results are shown for the Ha = 0, 30 and 50. It is observed that, with the increase in the transverse uniform magnetic field, the rate of melting of gallium and the heat transfer rate decreases.
