pressure gradient flow的意思|示意

While an incompressible liquid flows through a rotating inclined-tube with a constant pressure gradient the secondary flow due to Coriolis Force appears on cross section of the tube.

流体在压差作用下，流经绕与中心线成任意角的转轴匀速旋转的圆管时，由于哥氏力的作用，垂直于中心线的截面内将产生二次流。

The effect of the pressure gradient on critical Reynolds number is also displayed and the influence rule of the different pressure fields on the flow stability is exploited.

还研究了压力梯度对临界雷诺数的影响，探讨了不同压力场对流动稳定性作用的规律性。

Research on characters of non-Darcy flow and starting pressure gradient of low permeability reservoir were foundation of reservoir production.

低渗透储层渗流具有非达西特征和启动压力梯度，是研究低渗透储层开发过程中问题的基础。

Time dependent calculation for a suddenly imposed pressure gradient has shown that variation of the cross sectional area reduces inertial effect in the contraction flow region.

压力差为阶跃变化的情况下数值计算结果说明了收缩部的断面积的时间变化减少了收缩部的惯性效果。

The results showed that mobility and start-up pressure gradient are the main reasons of non-linear seepage flow effect.

结果表明流度与启动压力梯度是形成非线性渗流的主要因素。

Furthermore, the total pressure along the flow direction reduces gradually, and the corresponding static pressure increases with small gradient, the maximum value occurs at the end of FADS.

沿着流动方向，空气全压均逐渐减小，静压则逐渐增大，但增幅不大，末端处静压复得现象较为明显。
