流体透过颗粒层的全流态流动规律的构建

Establishment for whole flow regime law of fluid flow through granular layer

以Dupuit粉体层假定为基础建立数学物理模型,依据相对运动原理和相似运动规律,将流体透过颗粒层的流动与流体在当量平行细管中的流动及流体绕颗粒的绕流运动相比拟,发现它们之间的相似性与一致性。再从流体力学基本理论出发,通过对现有理论成果归纳与实验数据的重新整理,提炼出新型的流体透过颗粒层的全流态流动规律,从逻辑上统一了流体透过颗粒层流动规律的推理模式,在形式上更新了该流动规律的表现形式,初步完成了对该问题逻辑关联式的重置。

Based on the Dupuit＇ s granular layer assumption,a new type of the mathematical-physical model was established. Comparing the fluid flow through the particle layer with that in the equivalent parallel tubule and around a particle,the similarity and consistency were obtained. According to the relative motion principle and similarity movement regulation,the whole flow regime law of fluid flow through the granular layer was extracted based on the basic theory of fluid mechanics. The expression forms of fluid flow law through the granular layer were logically unified and their reasoning modes were renovated. The reset to logic correlation of the above problem was established and accomplished.
