| Viscous flow entrance into a plane channel with easily penetrable inserts (EPR) of a finite length is studied in the Navier-Stokes approach. Several cases are learned of a significantly dense EPR behind of which a circulation zone is formed. Solutions may be compared with another keystone flows described in literature. Critical EPR densities have been determined below of which no recirculation is formed. Extension and intensity of recirculation zones have been determined, as well as appearance of asymmetrical structures near both walls. |
