Cavitating flow in annular jet pumps
International Journal of Multiphase Flow, 2015Abstract 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, 1994For 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, 2013The 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, 2002Two-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.

Large eddy simulation of turbulent flow structure and characteristics in an annular jet pump
Journal of Hydrodynamics, 2017The large eddy simulation(LES) of the flow characteristics in an annular jet pump (AJP) is conducted, and the flow characteristics are systematically analyzed from both time-averaged and instantaneous aspects. The jet expansion, the velocity distribution and the energy are considered to analyze the time-averaged evolution of the flow field in the AJP ...
