AnnotationThe paper presents the results of a numerical study of the effect of the open-pored structure (OPS) on the laminirization of the flow in the channel. The Forchheimer-Brinkman model was used to model OPS, in which the viscosity and inertia coefficients were obtained by end-toend calculation of this structure. The distribution of parameters in the flow was obtained from the results of modeling the rotation of the channel. The quantitative criterion for the influence of OPS on the uniformity of the flow is the level of vorticity. The calculations of the flows were performed in a stationary setting according to the multifunctional software package LOGOS on a parallel supercomputer. From the analysis of the results obtained, it is concluded that with the use of OPS, the level of vorticity is significantly reduced and irectly affects the velocity profile downstream.
