Study on the Resistance Characteristics inside Large Grain Media

Chen, Zhen-Yuan 26 July 2001 (has links)
Abstract The studies measure the porosity, permeability of porous structures with different grain size and shapes such as those of crushed gravels and glass balls. Then discuss the relationship between various coefficients like intrinsic permeability, dimensionless turbulent coefficient, Reynolds number and so on in previous experimental formula¡]Ward¡A1964¡^and writer's formula from practical physics conceptions . Physics conceptions particularly consider respectively sheer flow effect and vortex effect in porous flow field. The study will be considered as the first phase in a full study of the resistance force inside porous structure.
