Abstract:
Experimental results of fluid flow
through homogeneous permeable media – sorted river
gravel of diameter 22.5, 12.2, 5.4 and 3.9 mm – the paper
presents.Experiments for hydraulic gradients
corresponding to Darcy’s law up to 7,5 (post Darcy’s
movement) has been undertaken.Using a capillary tube
model of filtration, parameters of the movement has
been determined: porosity, pores diameter, tortuosity,
Forchheimer type quadratic relationship of hydraulic
gradient, the dynamic and static specific area and
friction factor law in function of pore diameter Reynolds
number.
