摘要
随着计算机技术的迅速发展和计算流体力学理论的不断进步,国内外许多研究者利用CFD软件对搅拌器内部流场进行了大量的模拟。同时,也有不少学者针对搅拌设备内部流场利用LDV和PIV等测量技术进行了实验研究,结果表明,CFD模拟的结果与实验数据吻合较好。利用滑移网格法计算了六折叶圆盘涡轮搅拌器内部固-液悬浮流场。采用标准湍流模型及欧拉法来建立流体力学模型,研究了搅拌器在不同转速及不同安装高度下,流场的分布情况,分析了数值模拟和实验研究之间的功率消耗差异。通过数值模拟,为搅拌器的优化和放大提供参考。
With the rapid development of computer technology and the continuous improvement of computational fluid dynamics theory,many researchers at home and abroad by using CFD software have done large number of simulations of blender internal flow field.At the same time,there are many scholars aiming at mixing equipment internal flow field using the LDV and PIV measurement technology to carried on the experimental study.The results show that CFD simulation result coincides with the experimental data very well.Six leaf disc turbine blender internal solid-liquid suspension flow field is calculated by using sliding grid method.The standard turbulent model and Euler Method to establish the fluid mechanics model is used in this simulation.The blender in different speed and different height of installation,the distribution of flow field are researched.The difference of numerical simulation and experimental study about the power consumption is analyzed.Through numerical simulation,so as to provide reference for the design and enlargement of mixer.
