Abstract: The different structures of immersion unit should affect the flow state of gap flow field. In order to study the influences on the flow state, the computational fluid dynamics(CFD) simulations with different structures of the immersion unit were established. The analysis of different injection shapes and the height of the gap flow was carried out. The research results show that the injection angle with 90°~150° and the gap height with 0.7 mm~1 mm are the optimize structural parameters.
