摘要
利用有限元分析方法数值模拟了界面形状对氧化物高温熔体碟形浮区中的温度分布和重力对流速率的影响，发现界面形状对重力对流速率有较大的影响。对于凸面，相对于炉圈平面５％的偏离使重力对流速率增大２５％，偏离越大，重力对流速率越大；对于凹面，５％的偏离使重力对流速率减小１５．７％，偏离越大，重力对流速率越小．
The effect of surface shape on the temperature distribution and buoyancy-driven convection velocity in high temperature oxide melt was analyzed with finite element method. The result show that surface shape has considerable influence on the velocity field and thermal field. For convex surface, 5% surface bias may induce 25% velocity variation, the more the bias distance, the higher the velocity in the melt; For concave surface, 5% surface bias may induce 15.7% velocity variation, the more the bias distance, the lower the velocity in the melt.
