用涡格方法和涡滴方法模拟了大振幅Kelvin-Helmholtz不稳定性的涡面卷起特性。这两种方法都使问题规则化，并防止在许多以前的模拟中发现的不规则运动。对这两种方法的正则化性质进行了比较和讨论。
The vortex sheet roll-up characteristic of large amplitude Kelvin-Helmholtz instability is simulated by vortex-in-cell methods and a vortex blob method. Both methods regularize the problem and prevent the irregular motion found in many previous simulations. The regularization properties of the methods are compared and discussed.
