Cavitating flow in annular jet pumps

International Journal of Multiphase Flow, 2015
Abstract Based on the experimental and numerical methods, the pump performance and inner flow details of annular jet pumps under three area ratios (cross sectional area ratio of throat and nozzle) were studied in the present paper. The cavity clouds forming at the shearing layer, recirculation center and throat inlet were captured via high speed ...

Recirculation in an Annular-Type Jet Pump

Journal of Fluids Engineering, Transactions of the ASME, 1994
For some annular-type jet pump applications, it is important to avoid formation of a recirculation zone in the mixing region. The goals of this research were to find (i) when recirculation occurs and (ii) the size and location of the resulting recirculation zone. Experiments were performed using air in a straight-walled, annular-type, ducted jet.

Numerical investigation on the recirculation in annular jet pumps

Journal of Mechanical Science and Technology, 2013
The flow within the annular jet pump (AJP), in some degree, resembles the annular wall jet developing in a pipe with great axial pressure gradient. In some working conditions, there exists the backflow near the centerline. However this differs from the case in a center jet pump (CJP) that the recirculation emerges near the inner wall of the throat. The

Two-dimensional numerical simulations on the performance of an annular jet pump

Journal of Visualization, 2002
Two-dimensional numerical simulations were carried out to investigate the effects of the shape of mixing chamber on the performance of annular jet pumps for several jet flow rates. We confined the computational domain to a jet, a mixing chamber, and the outlet of the pump.
