The numerical simulation of the water temperature in the Rı́o de la Plata River and Montevideo’s Bay was done using the numerical model of finite elements RMA-10 in its 2D vertical integrated mode. Parameters involved in the formulations of thermal exchange with the atmosphere were adjusted using measurements of water temperature in several locations of the water body. After calibrating the mode...

s: -Most of the small hydro power plants are based on Run of River scheme, implying that they do not have any water storage capability. The power is generated only when enough water is available from the river. When the stream flow reduces below the design flow value, the generation will reduce as the water does not flow through the intake structure into the turbine. Small hydro plants may be s...

The trend toward higher speed, higher power density liquid turbomachinery has inevitably increased the potential for fluid/structure interaction problems, and the severity of those problems. Fluid structure interaction phenomena can lead to increased wear and to structure failure. There are many factors affecting hydraulic and dynamic performance of pumping plants. These factors contribute to d...

Abstract Lateral intake structures suffer from sediment deposition and instability of flow path which may have a negative influence on the efficiency power plants that use river intakes as primary source for their cooling system. This study aims to experiment usage submerged vanes mitigation method determine effectiveness in decreasing deposition. A numerical model was constructed using DELFT3D...

In this study, we review federal datasets to assess the impacts of once-through power plant cooling systems on summer freshwater temperatures in the United States from 1996 to 2005. We find that maximum reported temperature discharges averaged 37 C (1996–2005) and were 9.5 C (1996–2000) to 10 C (2001–2005) higher than maximum reported intake temperatures during the summer. More than half of all...
