在进行流体研究时，动力学相似和几何相似是两个最基本的条件。
The dynamic similarity and geometric similarity are the basic terms at studying fluid.
模型适用于不同地应力条件、不同几何参数与射孔方案、不同岩石和流体参数等条件下射孔完井的气层出砂预测。
The model can be used under general conditions of practical geo-stresses, complex geometry and perforation proposal, and variable rock and gas properties.
微通道内气泡生成机理受到通道几何尺寸、流体流动边界条件、流体物性等多种因素影响，过程非常复杂。
Affected by some factors, such as the channel geometry, fluid boundary condition and material properties, bubble formation process is complex.
意思好像是说项目中没有流体体积，需要检查几何体或者边界条件。
There is no fluid volume in the project. Please check geometry or boundary conditions.
本文从目前常用的平行平板流动腔内流体定常流动时的切应力表达式出发，指出该切应力表达式仅适用于小雷诺数条件，由此确定平行平板流动腔几何尺寸的合理选择；
The paper pointed out that the formula people used to calculate the shear stress was appropriate when Re was small, then gave the rational size of the flow chamber.
