鼓泡后玻璃熔窑内流动和传热的二维数值模拟

Two-Dimensional Simulation of Glass Flow and Heat Transfer in a Glass-melting Furnace after Air Bubbling

窑炉是玻璃生产过程中最主要的热工设备。玻璃液在窑炉内的流动状态和温度分布都较复杂,它们对玻璃生产质量、能耗影响较大。因此,窑炉内液流的分布和温度的分布一直为广大窑炉热工研究和设计人员所关注。现有的研究方法主要有三类:(1)对运动窑炉的现场实测;(2)借助物理模型研究;(8)借助数学模型研究。

This paper reports a numerical method to simulate the effect of air bubbling on glass melt flow and heat transfer in a glass furnace Results of numerical simulations for flow and heat transfer with and without air bubblers in a container glass tank furnace are given in this paper. The results show a signifloiant effects of air bubbling on glass flow and heat transfer.
