抄録

The flow of liquid in a rotating cylindrical container with a rotating disc at the liquid surface is investigated using a model of the melt flow in a Czochralski crucible. The tangential velocity of the liquid was measured by using a laser Doppler velocimeter, and the effects of rotational container Reynolds number, rotational disc Reynolds number, distance between bottom of the container and the disc, and radius ratio of the disc and the container on the velocity distribution were examined. The result indicates that the radial distributions of the time-smoothed tangential velocity are independent of the vertical position from the bottom of the container, which is known as the Taylor Proudman theorem, in the cases of the container rotating and the disc being stationary, the container stationary and the disc rotating, and the container and the disc counter-rotating with small angular velocity ratio. When the container and the disc counter-rotate with a large angular velocity ratio, the effect of the disc rotation on the flow becomes remarkable in the lower part of the container.
