Abstract JET plans to install two pump limiter modules which can be used for belt-limiter, inner-wall and X-point discharges and, also, for 1–2 s as the main limiter. A design is presented which is compatible with two diagnostic systems and which allows access for remote-handling operations. The high heat-flux components are inertially cooled during

Mixing-throat cavitation in a liquid jet pump results from high jet velocities, low suction (NPSH) pressure, or low discharge pressure. Incipient cavitation at the jet boundary has no effect on jet pump efficiency, but under severe conditions it spreads to the walls.

Numerical study on jet-wake flow and its evolution in a centrifugal pump with alternating stall
The Physics of Fluids, 2023Stall and jet-wake flow are two typical forms of unstable flow phenomena in centrifugal pumps, significantly affecting their stability. This paper investigates the interaction mechanisms between stall and jet-wake flow in a centrifugal impeller under ...

The water jet pump, when designed with experimentally obtained optimum dimensions, can achieve efficiencies in the range of 35% to 40%. The design depends on the selected nozzles and diffuser, as well as the other parts of the pump, so that the hydraulic losses incurred are kept to a minimum.
