A thin planar fracture with a highly permeable porous filling disturbs an incident unidirectional one-phase flow in a formation/aquifer and makes it essentially 2-D. The main objective of this paper is to get an analytical evaluation of the quantity

The results of numerical studies of water-cooling process in jet-film contact devices are presented. It is shown that air velocity affects heat exchange negligibly because the increase in heat and mass transfer coefficients is balanced by the decreas
