The report provides comparative characteristics of filtration processes in the octahedral cell, as well as in the central and near-wall cells with cubic packaging of balls in the range of Reynolds numbers of up to 20,000. In an optically homogeneous system, where the packing of glass balls and the immersion liquid had the same refractive indices, the three components of the velocity vector of the filtration flow in the cells were measured using LDA. Characteristics of a turbulent boundary layer on the ball and vor...

The development of the oil industry, transition to digitalization of fields and development of new technologies require an understanding and forecasting of macroscale processes throughout the porous region, as well as reliable theoretical and numerical models. On the other hand, validation of such models requires knowledge of fluid dynamics in the pore space over a wide range of Reynolds numbers. To study the basic laws of local hydrodynamics of turbulent filtration flow inside the pores, including boundary layers...
