Abstract Gravitational Water Vortex Power (GWVP) plant is a favourable micro-hydro
extraction method due to its simplicity and compatibility with ultra-low hydraulic head …

The occurrence of the free surface vortex is inherent to numerous physical situations and
may result in the entrainment of air which is detrimental for many engineering processes and …

Waste energy recovery is crucial to improving the overall energy efficiency of any industry.
Industrial wastewater discharge contains a considerable amount of hydraulic energy, a …

To study the flow characteristics of water and oil in a free surface vortex with an oil slick on
the water surface, the flow phenomenon was simulated using FLUENT software and …

In the present numerical research, the efficiency of perforated and plate trashracks are
investigated in reducing the strength of the formed free surface vortices at vertical intakes …

Utilization of renewable energy potential continues to be developed at this time. One of them
is a hydroelectric power plant with turbulent vortex technology. One of the vortex turbine …

Air entrainment is a concern of paramount importance in the process industries, including
nuclear power plant, hydraulic machines, water treatment plants, hydrocyclones, and power …

The available formulas for the profile of a vertical non-air-entraining vortex are not practical
because they involve unknown parameters and need measurements of the local viscous …

By decreasing the entrained air flow discharge and improving the hydraulic characteristics of
vertical shaft spillways, Marguerite-shaped inlets (MSIs) can mitigate the effects of swirling …
