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 …

Unsteady numerical simulation and visual experiment are used to reveal the formation
mechanism of the roof-attached vortex (RAV) on the roof of the closed sump of a pum** …

Vortex flow characteristics in a reservoir and horizontal water intake have been predicted by
using regression models in this numerical research. In this paper, three standalone machine …

In the present research, effect of entering formed free surface air-core vortex over the intake
in the reservoir on flow velocity distribution in the pipe is studied, numerically. LES (Large …

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 …

In order to study the characteristics of the different formed free surface vortices at vertical
hydraulic intakes, three sets of experiments were conducted. The spiral flow was detected …

In this study, the laboratory design and construction including: hydraulic, structure and water
circulation system of a model for free surface vortex studies at intakes are described in …

One of the most important hydraulic structures which are used to divert flow is lateral intake.
