查询词典 vortex

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。
