摘要

利用计算流体力学(CFD)分析软件对Cz过程的温度场和速度场进行了三维模拟。利用得到的Cz过程的速度场和温度场，我们基于Boussinesq近似，考虑热的传导、对流和辐射，给出了生长过程不同转速下自然对流和强迫对流的相对强度。同时模拟了Cz生长坩埚中由于液面下降而引起的自然对流和强制对流的变化。研究结果将指导Nd:YAG Cz的大直径、高质量生长。

Three-Dimensional Simulation of Nd:YAG Crystal Growth Based on Computational Fluid Dynamics Analysis Software

We performed 3D simulations of the temperature field and velocity field in the Czochralski (Cz) process by using computational fluid dynamics (CFD) analysis software. With the obtained velocity field and temperature field in the Cz process, we showed the relative intensity of natural convection and forced convection under different rotation speeds of the growth process based on the Boussinesq approximation and by considering the conduction, convection, and radiation of heat. We simultaneously simulated the change of natural convection and forced convection due to the fall of the liquid surface level in the crucible used for Cz growth. The results will help guide Nd:YAG Cz growth with large diameters and high quality.
