全自動可視化装置による超電導マグネット中での熱対流制御

We observed the effect of magnetic force on thermal convection by the development of automatic visualization system. We visualized the temperature distribution of convection by using a theromosensitive liquid crystal. In the weightless condition with an upward magnetic force, we first confirmed the realization of thermal conduction state of convection, i.e., horizontal isothermal distributions with distinct color contrast. Those distributions were easily vanished with the disappearance of weightless condition and the inducement of convection.
