中文摘要: 利用渗流流体力学理论研究流体的渗流问题.在渗流运动方程的基础上,利用无量纲参数写出渗流的无量纲运动方程,并对渗流的无量纲运动方程进行分析.通过分析与比较可知,渗透阻力项在渗流运动方程中起着主导作用,而粘性力项和惯性力项相对于渗透阻力项通常都是非常小的,一般可以忽略不计;许多实际渗流一般不是小雷诺数流动.
Abstract:The flow problem in porous media is studied upon of the theory of the fluid mechanics in porous media in the paper.The dimensionless motion equation of the flow in porous media is written by means of the dimensionless parameters based on the motion equation of the flow in porous media.The analysis of the dimensionless motion equation of the flow in porous media is carried out.Analysis and comparison show that the osmotic resistance term plays a leading role in the motion equation of the flow in porous media,and the viscous and inertia terms are usually very small and can be omitted.A great many practical flows in porous media are generally not those of small Reynolds number.
