In this work we aim at investigating a negatively buoyant plume and providing quantitative estimates of the effect of a background rotation on the dynamics of the turbulent plume, with a focus on the intensity of the fluxes of ambient fluid entrained within the plume depending on the parameters that control the flow dynamics. The experiments were performed taking advantage of recent works on the dynamics of atmospheric downburst and on the analysis of the entrainment coefficient in plumes with varying dynamical states.

Abstract
In this work we aim at investigating a negatively buoyant plume and providing quantitative estimates of the effect of a background rotation on the dynamics of the turbulent plume, with a focus on the intensity of the fluxes of ambient fluid entrained within the plume depending on the parameters that control the flow dynamics. The experiments were performed taking advantage of recent works on the dynamics of atmospheric downburst and on the analysis of the entrainment coefficient in plumes with varying dynamical states.File in questo prodotto:
