Engineering Physics Annotation << Back THE VELOCITY OF CONVECTIVE HEAT TRANSFER IN FLUID FILTRATION IN A LAYERED MEDIUM O.V. AKHMETOVA, M.A. ZELENOVA, N.A. UNSHCHIKOV An expression describing the velocity of convective heat transfer in layered inhomogeneous anisotropic porous media is obtained. The radial pressure gradient, which is included in the expression for the filtration velocity, was found on the basis of an asymptotic solution of the problem of the pressure field in the selection of fluid from a layered inhomogeneous reservoir with a constant flow rate. On the basis of a computational experiment, it was shown that the establishment of the velocity of convective heat transfer in the system under consideration occurs during the first seconds and can be considered independent of time. The radial coordinate is the main quantity on which the velocity of convective heat transfer depends. Key words: speed of convective heat transfer, pressure gradient.
