【摘要】 基于湍流与多相流的耦合模型,应用流体力学的商业软件采用vof追踪界面方法,对板坯结晶器流场和自由液面进行数值模拟。研究表明液面速度、湍流动能及液面形状和浇注时间有一定关系。通过数学模拟,深入认识结晶器的湍流过程、液面波动行为及其影响因素。更多还原

【Abstract】 Based on coupled models for turbulence and multiphase flow description,a three dimensional software and vof tracking method have been employed to simulate fluid flow and free surface fluctuation in the slab mold.The relationships among the velocity、turbulent kinetic energy、surface wave and casting times have been investigated. Through the numerical simulation,It is made us deeply to known the processing of turbulent flow、surface fluctuation and the influence of surface fluctuations更多还原
