Abstract
Airlift pumps operating in two-phase gas-liquid flow are investigated with a view to establishing an analytical technique to aid in theoretically modelling air-lift pump behaviour. Extensive work on two test facilities constructed at the University of Cape Town's Hydrotransport Research facility has been done. Various components needed for the analysis are investigated. These include: (i) static dilation; (ii) dynamic void ratios; (iii) two phase weight component; (iv) two phase friction component; (v) two phase acceleration component. Using theoretical models for each component and combining these into the analysis technique, operating characteristics of airlift pumps with the following variables : (i) pipe diameters; (ii) gas injection depths; (iii) static lift heights; (iv) suction pipe lengths; have been successfully predicted.
