查询词典 turbulent

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。

Lt is discovered that the riblets with drag reduction reduce turbulent density and turbuleni dynamic energy in tuthulellt boundary layer, but they affect the flat coefficient insignificantly.

分析了减阻沟槽对平坦系数、湍流度、平均湍动能等参数的影响。减阻沟槽使湍流度、平均瑞动能减小，而对平坦系数的影响不明确。

In order to study local scouring field near the pier with sediment control dam, the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek. This paper analyses the velocity distribution in the scouring pool of pier and takes turbulent strength distribution in different direction. Three new characters for the local scours of piers with the sediment control dam are analyzed and the dam's applicability is brought forward.

采用Sontek公司声学多普勒测速仪对有拦沙坝防护的模型桥墩附近流场进行了精细测量，对桥墩冲刷坑内三维流速分布进行了分析，给出了冲刷坑内三维紊动特征量的分布，分析研究了有拦沙防护坝时桥墩局部冲刷的三个新特点，提出了拦沙坝的适用条件。
