Abstract

The work is devoted to the flow of incompressible fluid in an open flow with porous obstacles (vegetation, hill). For mathematical modeling of such flows, a single equation of suitability in the porous and free zone is used. The model is based on Rakhmatulin’s two-speed model. Numerical results of the hydrodynamic features of a two-dimensional viscous flow are presented. In the free zone, the equation turns into the Navier-Stokes equation, and in the porous region, into the Darcy- Forchheimer equation. For the numerical solution, the SIMPLE algorithm was used.
