Structural features of fractured-porous reservoirs lead to the need to apply dual porosity/permeability models to correctly describe filtration and other processes in such media. The paper presents a model of an oil-saturated fractured-porous reservo

In near-wall turbulence modeling it is necessary to resolve a thin boundary layer containing high gradients of the solution. An accurate enough resolution of such a layer can take most of the computational time. The situation becomes even worse for u

Publikováno v: Smart Modeling for Engineering Systems ISBN: 9783030062279

Resolution of a near-wall boundary layer is one of hot topics in turbulence modeling. It often requires most of computational time. A non-overlapping domain decomposition method has turned out to be very efficient to tackle this problem for engineeri
