Abstract

Experimental results of a homogeneous (along the coordinate transverse to the stream) flow instability during the interaction with a film of surfactant adsorbed at the flat interface are presented. The flow was formed at a point-like heat by radiation and a source of surfactants (acetone drops). It is proved that a small value of the film shear viscosity is one of the requirements for the vortices formation process. The possibility to use the dimensionless parameter (the elasticity number) to describe the system behavior in 3D geometry is shown. A potential mechanism for the vortices origin is proposed. The results of the visualization of the water surface uniform flow around a solid sphere are presented.
