摘要
毛细管模型中,根据Poiseuille导管流动公式和牛顿第二定律建立单相流体的启动流动方程,求解得到位移、速度等参数随时间的变化,进而得出了毛细管中单相流体的启动流动过程中惯性力和渗流阻力之间的变化规律。根据毛细管模型中流动,阐述了启动压力梯度问题。
In the capillary tube, the equation of the single-phase instability flow is established on the basis of the Poiseuille equation and the Newton second law.The change of displacement and velocity with time is obtained. And the relationship of inertia force and seepage flow resistance is calculated. The capillary tube with flow is applied in the analysis of the threshold pressure gradient.
