摘　　要：采用Space claim建立全电玻璃熔窑的三维模型,利用计算流体力学软件Fluent18.0对玻璃熔化过程中电压分布、温度分布及速场进行模拟。研究表明:整个熔化部电压及温度成明显梯度分布,越靠近电极附近电压及温度越高,熔池内玻璃液温度基本维持在1 627~1 472℃,熔池内出现明显的回流现象,流速最大处位于熔池底流液洞附近;模拟结果与工业实验数据基本吻合,这对于理解玻璃成型过程中的温度及速度变化规律,具有指导工业应用的意义。The 3D model of glass all-electric furnace was developed by Space claim, and the electric： potential, temperature fieht and velocity field were simulated by computational fluid dynamics software Fluent 18.0. The results show that the electric potential and pressure had obviously gradient distribution, the nearer to the electrode, the higher the electric potential and the temperature are, and the melting tank of temperature maintained between 1 627℃ and 1 472 ℃, the phenomenon of the backflow in the molten pool emergenced, the maximum velocity of molten pool located near throat. The simulation results were in accord with the measured and experimental data. The simulation is helpful to understand the laws of temperature and velocity variation in the process of glass forming and guide the industrial practice.
