FLOW IN A CUBIC CAVITY WITH A MOVING COVER

The mechanisms of formation of three-dimensional jet flows 
inside large-scale vortex structures in a closed cubic cavity have 
been considered. The vortex structure of an incompressible viscous-fluid 
flow in this cavity has been investigated using the qualitative theory 
of ordinary differential equations. Singular points and their types 
and positions were determined at different Reynolds numbers on the 
basis of numerical calculations.
