http://popups.lib.uliege.be/1373-5411/index.php?id=3506 The new model equations for hydrodynamics with memory effects are investigated. The possibilities of collapses, structures and fragmentation are discussed. The results of numerical evolution of the torus as the initial conditions are presented. The process of vorticity development and fragmentation at high speed of flow is displayed.
