For years, the study of free surface vortices at hydropower plant intakes has been a topical
and intriguing subject among engineers and researchers. This subject will continue to attract …

For tidal power stations, the turbine operates under low-head near the free surface. The
water levels change both the reservoir and sea sides, furthermore, the intake channel length …

The mechanism of the generation and evolution of the air-core vortex formed between a free
surface and a horizontal flow intake is investigated using large-eddy simulation of two-phase …

In the present research, hydrodynamic behavior of free surface vortices including surface
displacement of the vortex core as a function of the vortex stability, relationship between the …

Intake direction is one of the most important factors which have significant effect on vortex
formation at intakes. Due to the importance of withdrawal direction to vortex formation, the …

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

The problematic consequences regarding formation of air-core vortices at the intakes and
the drastic necessity of a thorough investigation into the phenomenon has resulted in …

A new type of vortex drop shaft without ventilation holes is proposed to resolve the problems
associated with insufficient aeration, negative pressure (Unless otherwise specified, the …

Surface vortices are the main reason of flow instability and entraining air and debris into the
intakes. Using structural based anti-vortex facilities is a common method for dissipating …
