用水模型研究了在喷管入口区引入旋流的影响。本文针对连铸过程中的喷射区进行了研究。目的是使喷射速度更加均匀，从而减少自由表面的扰动。水模型计算结果表明，在扩张式喷管入口区施加旋流流型，可以获得均匀的出口流动。这表明，在外加磁场的作用下，可以通过在熔体中引入旋流来控制连铸机的出口流态。
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 caster may be controlled by introducing swirl flow in the molten metal using an externally imposed magnetic field.
