gas-lift pumps are devices for lifting liquid phase incorporating the gas phase to be injected in the bottom of liquid column. they are widely used in various industrial applications such as oil extracting in petroleum industries. gas-liquid flow being the main part of the flow through these systems, flowing in vertical pipes of gas-lift pumps has different regimes namely bubbly, slug, churn an...

This paper presents the results of a study on use an airlift pump in aquaponics, model that has been applied and developed for organic food production. Airlift pumps, which are commonly used mining industry pumping liquids such as water oil, have recently adopted aquaponics systems. Airlifts offer several advantages over other types including simple compact design with no moving parts, making t...

This paper investigates the self-cleansing performance of an airlift pump with a U-bend. For this purpose, experimental setup is used to assess effect air flow on pump's ability lift water and remove particles under different submergence ratios particle concentrations. In addition, simple yet accurate fluid mechanical model interpret experiments individual predict critical velocity required for...

This paper presents the optimal conditions for fast transfer of solid particle with an airlift pump. The experimental examinations were carried out in pump a length 5.64 m and inner diameter 0.102 order to determine impact submergence ratio, air flow, physical properties, such as shape, size, density, on vertical velocity detail. results showed that same maximum was achieved when churn flow reg...
