摘　　要：采用数值模拟方法,对单个熔融玻璃粉料颗粒的恒温球化过程进行了模拟研究。应用FLUENT软件,结合流体体积法追踪颗粒球化过程的液滴界面,模拟得到了熔融玻璃粉料颗粒在表面张力作用下自然球化的演化过程。提出了以熔融液滴的表面积变化来表征球化进程,分析了恒温条件下,熔融液滴的初始球形度、体积、粘度、表面张力因素对液滴球化时间的影响,并根据模拟结果拟合得到了特征球化时间的经验公式。The isothermal spheroidizing process of a single molten glass particle was investigated via numerical simulation.By utilizing the FLUENT software,the evolution of molten glass particle natural spheroidizing process induced by surface tension effect was simulated,which based on tracking the liquid interface of spheroidizing process by volume of fluid method.The spheroidizing process is characterized by the variation of the molten droplet＇s surface area.Additionally,the influence factors of spheroidizing time were also analyzed,including the initial sphericity,volume,viscosity,surface tension of the molten droplet.Finally,an empirical formula of characteristic spheroidizing time was obtained with the simulation results.
