Summary

This paper provides a review on turbulent swirling flows. The emphasis is on confined turbulent swirling flows exhibiting vortex breakdown, as encountered in swirl-stabilized combustion systems. In the first part, the physics of turbulent swirling flows is discussed, based on theory and experimental observations, emphasizing complex phenomena, which are typical of swirling flows, such as vortex breakdown (VB) and the precessing vortex core (PVC). In the second part, computational strategies for predicting these phenomena are reviewed. These include a broad spectrum of turbulence modelling strategies, as well as different numerical approaches.
