Abstract
In a plane formulation, we consider a viscous-fluid jet flowing out of a rectangular channel and interacting with a horizontal solid substrate surface in the presence of gravity. The mathematical problem is formulated within the creeping flow approximation. For the numerical solution, a boundary-element method is used. The kinematic parameters of the jet and the evolution of the free surface are studied for different values of governing parameters. The critical values of the distance from the channel outlet to the solid wall are found. For the heights, greater than the critical value, the jet loses stability, which is manifested in the periodic buckling of the jet. A flow regime characterized by damped oscillations is described.
