Influence of suction chamber profile on flow field of annular jet pump

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract Jet pump is a kind of fluid machinery, which uses jet shear and turbulent diffusion to transfer mass and energy. It is widely used in water project, civil engineering and other fields. In order to investigate the influence of suction chamber profile on flow field of annular jet pump, the conical suction chamber and the ...

Effect of sand diameter on the performance of annular jet pumps

open access: yesJournal of Physics: Conference Series
Abstract For the current problem of low efficiency of the annular jet pump in transporting particles, the effects of different sand diameters on the flow field, pressure and efficiency inside the annular jet pump are analysed, in order to improve the structure of the annular jet pump to adapt to the transport of solid particles.

Numerical investigation on the impact of the converging angle of the suction chamber on annular jet pumps

open access: yesIOP Conference Series: Materials Science and Engineering, 2013
The internal flow of an annular jet pump is an annular wall jet developed in a limited space, which is affected by its structure, shape, area ratio and flow rate ratio. In this paper, numerical simulation of an annular jet pump with area ratio A=1.75 was conducted based on realizable k-e turbulence model.
