基于STAR-CCM+的旋风分离器数值模拟方法的研究
|
摘要
文章研究了基于STAR-CCM+的旋风分离器数值模拟方法。结果表明:软件的网格处理方式比较灵活,使用软件内部的三维建模和自动网格生成功能可以大幅度提高模拟计算的效率。模拟计算旋风分离器的湍流模型适合采用雷诺应力模型(RSM),模拟计算旋风分离器的液滴轨迹可以采用离散颗粒模型(DPM)。使用软件内部的标准模块功能和自定义函数功能可以比较方便实现压力分布、速度分量图、上下行气流分割面、液滴轨迹跟踪等内部流场处理。
Numerical simulation method of cyclone separator using STAR-CCM+ were studied. The results showed that the grid processing method of the software is flexible, and the efficiency of simulation calculation can be greatly improved by using the functions of three-dimensional modeling and automatic grid generation within the software. Reynolds stress model is suitable for simulating the turbulence of cyclone separator, and the discrete particle model is suitable for simulating the droplet trajectory of cyclone separator. Using standard module function and self-defined function in the software, it is more convenient to realize the internal flow field processing, such as pressure distribution, velocity component diagram, the division surface of upstream and downstream flow, droplet trajectory tracking and so on.
