Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.

对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明：1、强层化季节的陆架海水体一般呈现显著的三层热盐结构，在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层；2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制，而在潮流底边界层内，潮混合是水体热量、物质、动量与能量垂直交换的主要机制；3、潮混合影响的深度由潮流大小决定，在黄海，一般可达10-15 m，因此，在水深较深的区域，在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域，这显著抑制水体内物质的垂直通量，为物质垂直交换的瓶颈，而在水深较浅的区域，潮混合影响范围可至跃层底部，因此物质在跃层以下整个水体中混合非常均匀，当跃层内间歇性强混合发生时，可以产生显著的跨跃层物质输运；4、近底潮致强湍流耗散缓慢地向上传播，底上不同深度处垂直湍扩散系数也具有显著的位相差异，且二者均随时间呈现四分之一周日周期的变化；5、在地形较为平坦的中央海盆区，内波活动非常微弱，因此跃层内湍流混合非常弱，垂直扩散系数为分子扩散水平，跨跃层物质通量受到显著抑制，而在地形变化较为显著的局地陆坡区，内波活动非常活跃，除内潮的影响外，高频内波与内孤立波的影响也很显著，因此跃层内存在很强的间歇性强混合，内孤立波存在的区域，水体湍流混合显著增强。

The intermittency, one of the core contents in the modern turbulence theory, is in fact an essential character to turbulence, and it has more rich and varied manifestations under the background of the more wide scales of the atmospheric turbulence.

湍流的间歇性质是湍流运动的本质特征，多年来一直是现代湍流理论研究的中心问题之一。在地球大气湍流广阔的尺度背景下，湍流的间歇性表现出更丰富多彩的形态。

In the inlet turbulence intensity influenced region, the larger the inlet turbulence intensity is, the larger the turbulence kinetic, friction coefficient and Nusselt number is.

在入口湍流强度的影响范围内，入口湍流强度越大，湍动能、摩擦系数以及Nusselt数越大。

与turbulence相关的网络解释 [注：此内容来源于网络，仅供参考]

turbulence：湍流

当气流经过机翼上的转捩点(turning point)后,层流被破坏,气流开始摆动,互相干扰,形成许多小漩涡. 这称为"湍流"(turbulence). 所以,现代飞机的机翼后部,一般都设有"扰流片"来破坏这些湍流,使之变回层流,以此保持飞机的稳定性.

turbulence：紊流

鱼类的本能使牠们能精确而又有效地控制尾鳍,来吸取它们周围水流的动能,这包括一般物体造成的迹流、紊流 (turbulence)、甚至从它们自己身体前部形成的迹流.

turbulence：扰动

如果需要,选取"扰动"(Turbulence)以创建扰动光散射效果,并指定在散射介质中的细节数量以及扰动的总尺寸. 应用扰动后,会显著增加渲染时间. 8. 如果需要,选取"阴影"(Shadows)以指定介质自身是否接收阴影. 选取"阴影"(Shadows)能显著增加渲染时间,

turbulence：紊乱

ation)与紊乱(turbulence)效果扭转(Twirl)与针孔(Pincushion)效果克隆(clone)、显示(reveal)、涂抹(smudge)以及更多模式重新取样(Resample)功能比例失真(Anamorphic)图像支持每个节点都有多种贝兹(Bezier)样式将跟踪数据用于Rotoshapes 和点(points)上Shake 还包括高级的跟踪技术,
