Abstract
Effect of the swirl on the turbulent flow fluctuations is investigated based on a Lagrangian model of a fluid element. Motion of a fluid element in a mean swirling flow is considered. It is shown that turbulence can be suppressed by swirl and that swirl may result in an anisotropy of turbulent fluctuations. The hydrodynamic causes of such effects are studied. A coefficient of elasticity for a turbulent swirling flows is introduced. The results of the present work can be useful for the analysis of turbulence structure in swirling flows.
