Experiments on Influence of Magnetic Field on Distribution of Temperature in KNbO3 Melt

Abstract

Abstract: The effect of magnetic field on temperature distribution in KNbO₃ melt was experimental studied. By utilizing a special temperature
measurement technique, the KNbO₃ melt temperature distribution in a 2mm diameter platinum crucible was measured under 0, 70, 117, 135mT transverse
magnetic field respectively. The results show that the temperature gradient along crucible radius decreases with magnetic intensity increasing, especially,
the temperature gradient close to crucible-melt interface where the buoyancy-driven convection is the main convection form decreases greatly. It may
implie that magnetic field can damp up the buoyancy-driven convection in KNbO₃ melt.

Key words: magnetic field, KNbO₃, damping, buoyancy-driven flow, distribution of temperature
