Identification of self-organized vortexlike structures in numerically simulated turbulent flow of a viscous incompressible liquid streaming around a well on a plane

A system of Reynolds equations closed by adding a low-Reynolds-number Menter’s dissipative model of turbulence are solved with the use of a factorized finite-volume method. The generation of vortexlike structures in the case of stalled turbulent flow streaming around a deep well on a plane is analyzed. The effect of vortex intensification due to asymmetry of the well is discussed.
