| 摘 要： | 使用拉格朗日与雷诺应力模型相结合模拟了后台阶颗粒流,考虑了颗粒的重力作用而忽略了其它的作用力。结果表明,该方法对于后台阶颗粒流的气相流场与实验符合程度相当好,而在颗粒流中,模拟结果也与实验表现出一定的符合程度。由于该方法需要的计算资源比较少,值得进一步研究。

| Abstract: | The particle flow over a Backward-Facing Step is simulated with Lagranian and Reynolds Stress Mode.The gravity is considered and other forces are ignored.The results show that the flow field of gas agrees with experiment well.The field of particles also agrees with experiment on certain degree.The method would be further studied due to the advantage of less computational cost. |
