Air-core vortices are a ubiquitous phenomenon in the intakes of hydropower stations. Due to
the transient and instability of two-phase vorticial flow, the prediction of air-core vortex …

The air-core vortex is the most complex vortex in the intake system of tidal power stations.
Nearly all power plants prohibit the operation of units with air-core vortices, as these vortices …

Following the retrofit of the pump sump, there is a high risk of inducing the Combined
Submerged Vortex (CSV), which consists of the roof-attached vortex (RAV) and floor …

In this paper, the simple coupled level-set and volume of fluid and bifurcation models are
used for the accurate prediction of the flow in an open pump intake with a vertical pipe. The …

The air-core vortex generated at hydraulic intakes is usually associated with efficiency
reduction and performance deterioration of the hydraulic machinery. Numerical simulations …

Air-entrainment is a negative phenomenon in hydraulic intakes with a vertical pipe.
Researchers sometimes chose to offset the pipe from the intake center to trigger the air …

The two special hydraulic phenomena, vortex air entrainment and flow restriction
vaporization, can have a significant impact on the operation of the waste heat recovery …

Air-core vortex occurred at the hydraulic intakes deteriorates the performance and operation
stability of hydraulic machineries. To investigate the evolution process and generation …

An air-core vortex is generated in a tidal power station when the discharge increases or the
submergence decreases at the intake. To better understand the complex evolution of the air …

Ventilated cavitating flow of a circular cylinder is investigated by numerical simulation. The
coupled level set and volume of fluid method is used to capture the interface between the …
