The previous work on the SKAWs was extended from the one-dimensional case to the two-dimensional case, and it was showed that the two-dimensional SKAWs with the dipole vortex structure have some important unique properties that the one-dimensional model of the SKAWs can not expect.

为了解释这一现象，将前面关于SKAW的工作从一维情行推广到二维情行，发现二维SKAW具有涡旋结构而且具有一些一维SKAW所不具备的特征。

Results of simulation indicate that a series of "second-vortex" are produced in the riblets structure, turbulent kinetic energy and turbulent burst intensities are debased, which reveals reasonably turbulent drag reduction mechanism.

数值仿真结果则发现，在脊状结构内形成了稳定的&二次涡&，边界层内湍动能和湍流猝发强度降低，很好地揭示了减阻机理。

The results of simulation show that a series of "second-vortex" are produced when streamwise "reverse-vortices" are effected by riblets. They weaken intensities of "reverse-vortices", and restrain the productions and developments of low-flow strips, so turbulent drag reduction is obtained.

仿真结果表明，沟槽表面与顺流的&反向旋转涡对&相互作用，产生&二次涡&，削弱了&反向旋转涡对&的强度，进而抑制了低速条带的形成和发展，从而降低湍流猝发强度，实现湍流减阻。
