بررسی افت انرژی در سرریزهای پلکانی با وجود موانع روی پله ها با کمک مدل فیزیکی و مدل ریاضی Flow-3D [PDF]
سابقه و هدف: برای عبور آبهای اضافی و سیلابها از سراب به پایاب سدها از سازهای به نام «سرریز» استفاده میشود. سرریز باید سازهای قوی، مطمئن و با کارآیی بالا انتخاب شود که هرلحظه بتواند برای بهرهبرداری آمادگی داشته باشد.

A three-dimensional numerical model to estimate the fall velocity of sediment particles [PDF]
The fall velocity of sediment particles plays a key role in sediment transport studies. Researchers have attempted to determine the terminal fall velocity, and most of the studies in this regard have been based on experimental, quasi-experimental, and in-

Numerical investigation of bed-load changes on sediment flushing cavity [PDF]
The tanks' useful life will be reduced if their sediments are not discharged with a suitable method. Various hydraulic and mechanical methods can be used in many countries to discharge sediments from reservoirs.

Numerical Investigation on Effective Parameters on Hydraulic Flows in a Sluice Gate with Sill on Free-Flow Condition [PDF]
The presence of a sill under the sluice gate is one of the solutions to control the flow rate. This study was conducted to numerically investigate the discharge coefficient (Cd) of sluice gates with different heights and widths of sills in free flow ...

The Simulation of Upwelling Flow Using FLOW-3D
Large scale fishing ground can be made by upwelling flow. Recently the fishing ground development projects, using artificial upwelling by large structure under the sea, are in progress in Japan and Korea. In this study upwelling flow is simulated with FLOW-3D model.

Ship resistance analysis using CFD simulations in Flow-3D
While designing the power requirements of a ship, the most important factor to be considered is the ship resistance, or the sea drag forces acting on the ship. It is important to have an estimate of the ship resistance while designing the propulsion system since the power required to overcome the sea drag forces contribute to ‘losses’ in the propulsion

FLOW-3D Analysis on Scouring around Offshore Wind Foundation [PDF]
In order to evaluate the local scour around offsshore wind foundation, mono pile and jacket foundation were simulated by using FLOW-3D. Numerical analysis results show that local increases of velocity around mono pile and jacket foundation was developed but velocity decreases in backward of pile and leg due to the wake vortex was observed.
