| 摘 要： | 阐述了SPH(Smoothed Particle Hydrodynamics)方法的理论基础和计算方法,应用该方法编写程序计算了液滴在剪切流中的运动规律。通过激波和Poiseuille流动这两个验证算例的计算发现,SPH方法能很好地应用于流体运动规律的计算模拟。另外,还对不同的核函数的计算结果进行了比较,分析了影响计算精度的因素,在此基础上,计算模拟了剪切流中单液滴的运动行为,包括变形、破裂行为。 |

| Abstract: | The theoretical basis and calculation of SPH method was described,the movement law of the liquid drops in shear flow was calculated using a program.It was found that SPH method could be applied in the calculation simulation of the liquid motion law well through the calculations of two examples of impact wave and Poiseuille flow.In addition,the calculation results of various kernel functions were compared,the factors affecting the calculation accuracy were analyzed,the movement of single liquid drop,including deformations and cracking,was calculated and simulated based on the mentioned above. |
| Keywords: | Two Phase Flow Movement of Liquid Drop Deformation of Liquid Drop SPH Method |
