Structure optimization of an annular jet pump using design of experiment method and CFD
IOP Conference Series: Earth and Environmental Science, 2012 This paper adopts DOE (the design of experiment method) to find out the optimum structure combination of an annular jet pump for maximum efficiency. The annular jet pump (AJP) model used by previous researcher, which area ratio is 1.75, was chosen as the simulation prototype. The performance data from the experiment were used to validate the simulation

Bypassing annular gas by means of jet device in oil wells with electric submersible pumping units
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Nowadays the main equipment for oil production is the installation of electric centrifugal pumps. When operating oil wells with such installations, various complicating factors arise, in particular, the accumulation of free gas in the space between the outer surface of the tubing and the casing string.

CFD study on the effect of particle properties on the performance of annular jet pump
Journal of Physics: Conference SeriesAbstract The annular jet pump is a type of fluid mechanical pump that operates by exchanging momentum with the fluid. Annular jet pumps possess distinctive advantages in the transportation of solid particles. However, the efficiency of these pumps is significantly impacted by both the physical properties of the particles and their ...
