抜粋

Molten silicon convection during single crystal growth by the Czochralski method was visualized three-dimensionally by the individually developed double-beam X-ray radiography system with solid tracer method. The purpose of the present paper is to clarify the three-dimensional structure of torus-like flow pattern of molten silicon which has low Prandtl number. The root-mean-square velocity for one specific tracer was 21 mm/sec. The most impressive result was as follows; a flow field with larger azimuthal velocity than the rotational velocity of the crucible exists just beneath the crystal, while the flow field with smaller or negative azimuthal velocity exists near the crucible wall. This azimuthal flow modulation can be explained by the Coriolis force.
