| 摘 要： | 为精确求解流固耦合问题中物体大幅度运动时的受力情况和运动轨迹,采用基于任意拉格朗日-欧拉方法(Arbitrary Lagrangian Eulerian)的动网格技术,计算水气两相粘性流体中下沉物体的运动规律,并与模型试验的结果进行对照。结果表明,数值模拟所得物体的下沉轨迹和速度与模型试验吻合较好,从而验证了程序的可靠性和精度,可用于实际的溃坝堵口组件运动的数值模拟。

| Abstract: | In order to obtain the force and track of the block which is dropping in the fluid,the ALE(Arbitrary Lagrangian Eulerian) dynamic grid method is adopted.The locomotion of the block moving in the viscous two phase air-water fluid is computed with a CFD(Computational Fluid Dynamics) method and compared to the results gained from the model experiment.The results show that the dropping track and velocity of numerical simulation is in agreement with that of model experiment,which validates the reliability and ac... |
