The viscous incompressible fluid flow past an obstacle on a plane is numerically investigated. The governing equations are written in variables “pressure-velocity” for arbitrary curvilinear system of coordinates. Numerical integration is carried out within the framework of a known method of physical variables splitting on a case of arbitrary curvilinear system of coordinates. An essential interest represents the unsteady and 3-D forms of separation. The instant lines of the limiting streamlines were used allowing to classify a topological flow field structure for visualization of separated flows. The topological structures arising near a body surface has been obtained for different Reynolds's numbers. It is shown that near of a body surface the connection of singular point amount is fulfilled. The results are well agreed with numerical, experimental and analytical researches of other authors.
