摘要本文提出了一种自适应小波方法，将二维Navier-Stokes方程的速度-涡度方程与惩罚技术相结合，有效地处理任意形状的固体边界。我们证明了这种方法的有效性，称为相干涡模拟（CVS），计算在高雷诺数下的脉冲启动圆柱绕流，并与经典的涡方法的结果进行比较。
Abstract We present an adaptive wavelet method to integrate the velocity–vorticity formulation of the two-dimensional Navier–Stokes equations coupled with a penalisation technique to handle efficiently solid boundaries of arbitrary shape. We demonstrate the validity of this method, called coherent vortex simulation (CVS), to compute the flow around an impulsively started cylinder at high Reynolds number and compare the results with a classical vortex method.
