Abstract

Hydrodynamic regimes establishing in lab-scale internal circulation airlifts operated at low superficial gas velocity are addressed. Experimental methods based on visual observation of gas-liquid expansion and on measurement of the pressure drop along the loop are used. Local dynamical features have been investigated by analysing the time-resolved signals of the thermal power exchanged between the gas-liquid system and immersed surfaces (a hot film anemometer was used for this purpose).
