摘要
文章应用计算流体力学的方法对外循环DTB流化床结晶器进行了模拟,运行结果揭示了结晶器内流体的运动轨迹,体积分数分布情况以及各出口处流体的分布情况。实验结果表明采用流化技术后的DTB结晶器内能够实现很好的晶浆悬浮,有利于晶体的成核及成长。计算流体力学的方法为DTB结晶器的设计、改造提供了更加科学和准确的依据,具有重要的研究价值。
The article mainly discussed the simulation an external-cycling fluidized DTB crystallizer by applying the method of Computational Fluid Dynamics（CFD）,the result of which revealed the traces and volume fraction distributions of the fluids in the tank as well as the distribution of the fluids at outlets.The experiment also indicated that the fluidized DTB crystallizer can achieved an ideal suspension of magma.CFD Simulation provides an scientific and accurate guidance for the design and upgrade of DTB crystallizer,and therefore,it＇s of vital importance.
