| 摘 要： | 采用SPH方法模拟了流体界面的Rayleigh Taylor不稳定性,给出了界面初始扰动的发展过程,得到了蘑菇状的扰动图像,并对两种不同初始分布的扰动过程进行了比较。分析表明,计算结果合理,SPH方法适合于界面不稳定性的模拟。

| Abstract: | Rayleigh-Taylor instability of fluid interface was simulated by the smoothed particle Hydrodynamics(SPH) method. The growth of the interface instability was presented, and the fungus appearance of the instability was obtained. The characters showed by the numerical results indicate that the numerical results are logical, and the SPH method has the potential to simulate Rayleigh-Taylor instability. |
