A physical model of all-electric glass melting tank furnace was established on the basis of theory of similarity. The distributions of temperature and velocity of the simulating liquid in the furnace model were measured, and the influence of electrode-arrangement and structural dimensions of the furnace on the distributions has been discussed.

运用相似原理建立了一个全电熔玻璃池窑的物理模型,测定了窑内模拟液体的温度分布和流速分布,讨论了电极配置、炉子结构尺寸等对于温度、流速分布的影响。

A set of fundamental mathematicel relationships was set up for a simulative caleulation of the working status of a galss electrie melting tank furnace, based on the basic mathematical equations of heat transfer and fluid mechanics in combination with the working conditions of the furnace. The calculations of the physical properties of glass melt at high temperatures were formulated as follows: the value of electric conductinity and density were based on experimental date; the values of viscosity were cbascd on the Fulcher's experimental equation, in which the coefficients were calculate according to the Lakato's method; whereas the coefficients of heat conductivity were considered as constant within the range of the working temperatures of the furnace. These fundamental equations were then discretized in two dimensions with the SIMPLE methodand solved according to the "Line-by-line" method with the addition of the "double block correction" method, after the definition of the boundary conditions of temperature, velocity and electric potential depending on the operational status of the furnace.The calcultaion results obtained match well with J.Staněk's results based on a physical modelling study of an electric glass melting tank furnace. Therefore this study is considered significant to the design and operation conditions of electric glass melting tank furnace

从最基本的流体力学及传热公式出发,结合玻璃电熔窑的实际情况,确定了高温下熔融玻璃物理性质系数的计算公式;根据实验数据建立了电导率、密度随温度变化的数学式;用Lakoatos法确定了Fulcher粘度公式的计算系数;在电熔窑作业温度范围内把导热系数近似看作常数.从而建立了玻璃电熔窑工作时的基本数学方程式;同时在切合生产实际的条件下,制定了熔炼玻璃的温度、流速和电位的边界条件;并把这些基本公式用SIMPLE法在二维空间上进行离散,用Line-by-Line法对离散方程进行求解,求解时应用分块修正法加快收敛速度,得出的结果与捷克的Staněk的物理模拟研究结果情况一致,对玻璃电熔窑设计操作有重要价值.
