If the torque exerted on a fluid element and the source of streamwise vorticity generation are analyzed, a turbulence-driven secondary flow is found to be possible in a curved pipe.
|
| 例句来源 | |
A model was developed that estimated the volume expansion of a fluid element due to combustion in the turbulent mixing zone and predicted the resulting impulse increment.
|
| 例句来源 | |
By changing the orifice diameter and the conical angle of the inlet, it is possible to modify the spatial distribution of the velocity gradient, and hence, the residence time of a fluid element in the high strain-rate region.
|
| 例句来源 | |
In this non-affine motion, junction points follow particle paths as seen by an observer rotating at the fluid element's net rigid-rotation rate.
|
| 例句来源 | |
The model illustrates how rotations that cause changes in the relative orientation of a fluid element with its surroundings can be incorporated into a constitutive equation using the deformational vorticity.

| | The shallow-submarine hydrothermal activities generally appear in the oceanic volcano crowns or flanks.The submerged flanks of island arc volcanoes provide an exceptional opportunity to study the essential differences and similarities between subaerial and submarine venting and the transition from one to the other.Studying the shallow-submarine hydrothermal activities makes us understand comprehensively how the heat of the Earth's interior diffuses slowly.At present the fluid,associated gas and deposits of ... | | 浅海型海底热液活动一般出现于海底火山顶部或者翼部,其所处的特殊地理位置是深海热液活动和陆上热泉的过渡地形。研究浅海型海底热液活动使我们更全面了解地球内部热量的缓慢散发形式。目前浅海型热液活动研究多侧重于流体、伴生气体、沉积物等方面:对于流体研究主要通过流体元素特征探讨流体源,虽然浅海热液活动流体在海底喷出,但流体主要组分有时是海水,有时是陆上大气水—海水只是作为少部分加入其中。对于伴生气体的研究表明:热液喷出时伴生气体组分多是火山气来源,火山气的加入导致热液流体酸性增强,使热液流体较容易淅沥出围岩中的元素,因此尽管浅海型热液流体流经路程短,但是流体中依然包含了较多物质,从而在海底表面沉淀沉积物,甚至可以形成烟囱体,由此可见浅海型热液活动与火山活动紧密相关。对于沉积物的研究显示浅海热液活动产生的沉积物组分简单,也有像深海热液活动中烟囱状沉积体的形成。沉积物对周围水域中元素浓度起到积极影响,如Fe、As含量等,这是热液流体与海水相互作用的结果。现代浅海型热液活... | | 文摘来源 | |   |
