本文继文之后,在电子计算机上进行了大量计算,分析了各种参数对单一介质和双重介质非达西低速渗流的压力曲线动态特征。单一介质非达西低速渗流的压力曲线特征是压力曲线呈无台阶凹型向上翘,没有直线段;双重介质非达西低速渗流的压力曲线特征是单台阶凹型向上翘,没有直线段。相同的弹容比ω和相同的无量纲窜流系数 A,双重介质非达西低速渗流压力曲线的台阶比双重介质达西渗流压力曲线的台阶高得多。低速渗流时,难以辩识封闭边界的影响。
Following this article, a large number of computations were carried out on an electronic computer to analyze the dynamic characteristics of various pressure curves for a single medium and non-Darcy low-velocity seepage double media. The pressure curve of non-Darcy low-velocity seepage flow in a single medium shows that the pressure curve is concave without step-up, and there is no straight line. The pressure curve characteristic of non-Darcy low-velocity double-media fluid flow is that the single concave is upturned without straight line. With the same elastic modulus ω and the same dimensionless channeling coefficient A, the step of non-Darcy low-velocity seepage pressure curve in dual media is much higher than the step of Darcy flow in dual media. When low-velocity seepage, it is difficult to identify the impact of the closed boundary.
