Аннотация:The pressure driven flow of a viscous incompressible fluid in a 2D channel with sudden contraction and expansion is investigated numerically. The attention is concentrated on studying conditions of occurrence of the elongational flow in a narrow section of the channel. To this end, interconnection between flow patterns and axial velocities is analyzed at different Reynolds numbers.
