Краткое описание
The turbulent flow in swirling jets with swirl number large enough for vortex breakdown is investigated numerically. Three variants for the entrance boundary conditions and disturbances are simulated starting from stagnant initial conditions. The formation of the recirculation zone and the associated vortical structures are documented and compared to flow visualisations.
