摘要:
为确定格子Boltzmann方法对水力旋流器中旋流场模拟的适用性,基于水力旋流器的实验模型,采用格子Boltzmann方法,对水力旋流器内单相旋流场进行了模拟,并将本文模拟得到的平均速度分布与实验结果进行对比,给出了平均切向速度和平均轴向速度与实验值的相对误差。结果表明:格子Boltzmann方法能够模拟出水力旋流器中存在的旋流运动,并捕捉到流场的二次回流现象以及涡核的非稳态特征;模拟获得的平均轴向速度和平均切向速度分布与实验结果基本吻合,且对中心二次回流的模拟结果好于Hreiz(2011)文献模拟结果;模拟得出了平均径向速度在轴向上的方向交替变化,这与Hreiz(2011)结论吻合,并给出了水力旋流器中存在的旋进涡核现象。由此证明,格子Boltzmann方法可用于水力旋流器内旋流场的模拟。
