摘要
基于计算流体动力学(CFD)数值模拟方法,在Fluent软件平台上应用雷诺应力湍流模型、离散相模型和Grant&Tabakoff磨损模型对旋流器壁面磨损情况进行数值模拟分析,得到不同粒径颗粒对旋流器内壁面的磨损位置、形态和磨损速率。分析结果表明,粒径大小对旋流器内壁面的磨损部位及磨损速率均有影响,同时得到粒径与磨损速率之间的变化关系。
Based on the numerical simulation method in CFD, the Reynolds stress turbulence model, discrete phase model and Grant ＆ Tabakoff wear model were used to simulate the wall wear of the hydroeyclone on the Fluent software platform, in order to get wear position, wear shape and wear rate of the particles with different particle sizes on the inner wall surface of the hydrocyclone. The results show that the particle size has an effect on the wear area and the wear rate of the inner wall of the hydrocyclone while the relationship between the particle size and the wear rate is obtained.
