The numerical representation of pump-turbine performance characteristics [PDF]
This thesis investigates the hydraulic transient analysis of hydro-power plants with particular emphasis being placed on the turbine and\ud pump-turbine boundary conditions. A lack of suitable data, in the form of\ud the machine performance characteristics, during the early stages of a\ud hydro-power station's development led to the investigation of ...

Numerical simulation of pressure pulsation in vane area of a pump-turbine at pump mode [PDF]
, 2020 When a reversible pump-turbine is running under the low-flow conditions in pump mode, it is easy to produce low-frequency and high-amplitude pressure pulsation, which affects the stability of the unit.

Investigations on static and dynamic properties of liquid annular seals by a new transient numerical method with circular whirl model [PDF]
AIP AdvancesAnnular seals are employed in centrifugal pumps to inhibit leakage for reducing the effect of leaking fluid on the main flow. However, the seals generate fluid excitation forces while controlling the leakage flow, which seriously compromises the ...
