Visualisation of the Melt Flow under Rotating Magnetic Field

摘要

Experiments were performed for visual observation and investigation of liquid Gallium flow at a temperature of 40°C in a rotating magnetic field. Two different measuring methods were developed to determine the revolution number of rotating melt. In both cases the frequency of magnetic induction was 50, 100 and 150 Hz and the values of magnetic induction could be changed between 0 and 70 mT. The magnetic Taylor number changed between 0 and 3.54x10~7 during the experiments.
