Third, in order to calculate microscopic sweep efficiency in pore models, we define sweep boundary of displacement fluid, and determine it by velocity method.

第三，为了计算孔隙模型的微观波及效率，本文给出了驱替液波及边界的定义，并采用速度法确定其在流场中的位置。

Bubble collapse process near a rigid boundary in solid-liquid two-phase fluid has been observed with high speed camera in this paper.

本文利用高速摄影机观察了空泡在固液两相液体中，靠近刚性边壁附近的溃灭过程。

We investigate the flow mechanism of this conveyor in a horizontal configuration by a discrete element method (DEM), applying a periodic boundary and omitting the existence of fluid medium.

我们用离散元(DEM)方法研究了这种运输机在水平配置时的流动机制，施加周期性边界条件并忽略流动介质的存在。

That's a real fluid boundary between the divine and human realms, if you ask me. But it only happens there, in one spot.

这在神族和人类之间可真是一个不固定的界限，如果你问我的话，然而这种情况只在一个地点发生。

What that means, Kaufman asserts, is that in pagan religion there's very often a fluid boundary between the divine, the human, and the natural worlds. They blur into one another because they all emerge ultimately from the same primordial world stuff.

考夫曼认为，在异教概念里,神族、人类和自然世界的划分标准通常是不固定的，三者之间互相影响，因为从根本上来说,它们都是从同一个世界本源上发展而来。
