摘要: 研究了流体界面不稳定性的一类数值模拟方法——虚拟流动方法(Ghost Fluid Method).在算法中直接针对多维问题设定虚拟区域的流动参数,在流体力学方程的计算中采用了非分裂型的高分辨SCB格式,最后利用该方法完成了R-M和R-T不稳定性问题的数值计算,得到了满意的计算结果.
关键词: 界面不稳定性, 虚拟流动方法, Level Set方法
Abstract: A kind of numerical simulation algorithms for instabilities of fluid interfaces,Ghost Fluid Method, is discussed.The setting of fluid variables in ghost regions is directly based on multiple dimensional cases.Moreover,non-splitting high resolution schemes are used to solve the fluid dynamic equations. At last, the algorithm is applied to the simulation of interface instabilities of fluid dyanmics,and satisfied numerical results are obtained.
Key words: interface instability, ghost fluid method, level set method
