Concentrated separation vortex induced by non-uniform suction flow and its role in performance breakdown of a water-jet pump

Advances in Mechanical Engineering, 2017
Many water-jet pumps have a suction velocity profile, which is non-uniform and unfavorable for the pump performance. This article applies the numerical method to investigate the generation mechanism of performance breakdown in a water-jet pump under non ...

Shock/Vortex Interaction and Vortex-Breakdown Modes [PDF]

, 1993
Computational simulation and study of shock/vortex interaction and vortex-breakdown modes are considered for bound (internal) and unbound (external) flow domains. The problem is formulated using the unsteady, compressible, full Navier-Stokes (NS) equations which are solved using an implicit, flux-difference splitting, finite-volume scheme.

Control of shock-induced vortex breakdown on a delta-wing-body configuration in the transonic regime

, 2021
Shock-induced vortex breakdown, which occurs on the delta wings at transonic speed, causes a sudden and significant change in the aerodynamic coefficients at a moderate angle-of-attack. Wind-tunnel tests show a sudden jump in the aerodynamic coefficients
