Hydrodynamic effects of inclination angle on co-current gas-liquid packed beds


Hydrodynamic effects of inclination angle on co-current gas-liquid packed beds

Schubert, M.; Hamidipour, M.; Duchesne, C.; Larachi, F.

The incidence of inclination angle on the hydrodynamic behaviour of cocurrent gas-liquid flows through a packed bed is investigated experimentally in terms of liquid holdup, pressure gradient, and cross-wise and stream-wise gas-liquid segregation. Electrical capacitance tomography was applied for the analysis of the dynamic features of the two-phase flow as well as liquid saturation distribution. As a result of inclination angle, a segregated flow emerged in packed bed as a new flow regime intertwined between the trickle and the pulse flow regimes. Both segregated flow regime and pulse flow regimes were characterized and their relevant hydrodynamic features discussed.
