永久磁石を用いた鉛直平板自然対流の伝熱促進に関する実験的研究

抄録

In this study, natural convection of a paramagnetic liquid along a vertical heated plate is experimentally investigated in the presence of magnetic fields. Permanent magnet(s) is/are installed behind the heated wall and the local heat transfer along the heated wall is estimated with/without magnetic field. In case of a single magnet, the heat transfer is suppressed near the bottom edge of the magnet and enhanced around magnet top edge under the influence of the buoyancy. This effect also depends on the magnet elevation. By employing multiple magnets, the component of the magnetic force becomes remarkable and the effect is pronounced depending on the number of magnets and the elevations.
