摘要
A water model is used to investigate the effect of imparting a swirl flow in the entrance region of a nozzle. The study is aimed at the injection region of continuous casting process. The purpose is to make the injection velocity more uniform and so reduce the disturbance of the free surface. It was shown using the water model that a uniform outlet flow could be obtained by imposing a swirling flow pattern in the entrance region of a divergent nozzle. This suggests that the outlet flow pattern in a continuous easter may be controlled by introducing swirl flow in the molten metal using an externally imposed magnetic field.
