Abstract
Dropshafts are commonly used in sewers and stormwater channels as energy dissipator systems. Since recent effort has been devoted to characterize dropshaft hydraulics and air-water flow properties, and the present paper develops an analysis of the bubble clustering process using new experimental data collected in a large-size facility. The results highlight some significant patterns in clusters production. Finally, interfacial areas for mass-transfer were measured.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
