应用基于边界保角变换技术的Galerkin有限元方法 ,研究熔体生长中动力学效应和自然对流的耦合作用 ,探究了对流对生长系统中的温场分布、相界面形状以及界面过冷度的影响 .研究结果表明 :自然对流可使相界面的弯曲度减小 ,界面的相对位置降低 .同时 ,对流使得小面端点处的夹角变得圆滑 ,小面域和粗糙面域的界线变得不明显 ,相应地 ,小面尺寸有所减小 . The Galerkin finite element method based on the boundary conformal mapping technique was used to study the coupling effect between kinetic effect and natural convection in melt growth. The effect of convection on temperature field distribution, phase boundary shape and intercooling degree in the growth system was also studied The results show that the natural convection can reduce the curvature of the phase interface and reduce the relative position of the interface, meanwhile, the convection makes the angle at the end of the facet to be smooth and the boundary between the small plane and the rough plane become Obviously, the facet size is reduced accordingly.
