Nov 1, 2023 · The dependence of airlift pump performance on up-riser shape variation in the form of a step riser pipe was investigated numerically by Hanafizadeh at al. [14]. The results of small pipe diameters of 6 mm and 8 mm showed that the pump capacity depends on the diameter of the outlet up-riser pipe. The study was repeated on a gradually changing ...
Aug 24, 2020 · In the introductory section, the description, the application, and the performance of the airlift pump are described. The influencing parameters of the airlift pump performance are classified in the geometry and operational. The geometry parameters are including submergence ratio, pipe diameter, pipe length, design, and position of the injector.
Mar 1, 2008 · The authors recently designed and tested an experimental airlift unit that included a 7.9-cubic-meter circular fiberglass tank with 1.0 meter of water depth and a 0.14-cubmic-meter Polygeyser biofilter with enhanced media of 55 percent porosity. Water from the tank center drain gravity flowed to the filter through a 7.6-cm-diameter pipe.
Dec 14, 2020 · The performance of the new model was evaluated based on six different cases in three different bubbly flow systems, i.e., airlift column, pipe and bubble column. With the aid of the proposed model, both mean flow properties, such as the gas hold-up and axial liquid velocity and liquid turbulence kinetic energy can be well predicted in the ...
Jun 12, 2017 · An air lift pump is a device used to rai se the liquid or. slurries from a well or vessels through a vertical pipe, partia lly. submerged in the liquid, by means of compressed air. introduced into ...
In the current study, a novel design of an air injection system for an airlift pump was designed and tested. The pump has a circular cross-section and composed of three parts; suction pipe ...
Aug 14, 2021 · To induce circulation of the liquid in the riser pipe, the minimum air velocity was varied at each submergence ratio and measurements began after the airlift operation stabilized. For each intended submergence ratio, the test was performed four times with 5 min intervals between repeated tests within a measuring series.
