FILTRATION AND INFILTRATION IN A ZONALLY INHOMOGENEOUS POROUS MEDIUM
B. A. Suleimanova and A. O. Efendievab UDC 532.546 Based on experimental investigations carried out under laboratory conditions, the features of filtration and infiltration of a liquid have been studied in a linear model of a bed. The model consisted of two zones of different permeabilities and was manufactured in the form of a cylindrical tube of length 1.1 m and inside diameter 0.032 m. It has been shown that, in filtration of water from a lower permeability to a higher one, the productivity coefficient increases, on the average, by 15% as compared to infiltration. The mechanism of the phenomena observed has been proposed. a "Gipromorneftegaz" State Research and Design Institute, 88 Zardabi Str., Baku, Az1012, Azerbaijan Republic; b Institute of Mathematics and Mechanics, National Academy of Sciences of the Azerbaijan Republic, Baku, Azerbaijan.
