Annotation	This paper presents the results of numerical modeling in macro and micro models. At the microscale, elementary physical processes through a porous insert that occur in continuous space and time are investigated. Based on this micro-modeling, the filtration characteristics of the porous insert for the macromodel were determined. Macromodeling uses an enlarged discretization of space by functional feature to study the flow in a curved channel. The effect of porous insert on reduction of flow inhomogeneities is evaluated by macromodel. Results of numerical study of structure of turbulent flows behind the elbow are given. The problem of reducing pulsation disturbances of the flow occurring in the gas-dynamic path behind the elbow using a porous insert is considered. Current calculations were based on the LOGOS software package.
