Popis: () An experimental in®estigation has been made of the influence of the initial bubble size and bubble concentration distribution on the gaslift efficiency for a ®ertical air water flow through a pipe of 72-mm dia. and 18-m height. Three significantly different bubble injectors were used. It was found that with decreasing bubble size, the liquid production increases at constant gas flow rate and, hence, the gaslift efficiency increases. Also, the initial concentration distribution can be significant, as this distribution can influence the coalescence of bubbles close to the injector. With decreasing bubble size, the transition from bubbly flow to slug flow can be postponed. This is one of the main reasons for the beneficial effect of the bubble size on gaslift efficiency. A theoretical model has been de®eloped to predict the influence of the bubble size on the gaslift efficiency. The agreement is reasonable.
