Branch pipe T-joints are used to connect and bifurcate hydraulic channels in big power plants size. These components submitted enormous strengths that must be counteracted by integrated structures the T-joint, for this case specified arrangement type "Nun neck". The main objective work is about validate structurally numerical analysis branch T-joint design with reinforcement “Nun Neck” operatio...

This project sets out to develop the lower section of the mountain cascade of the Dhauliganga r...

Abstract In recent years and in many countries the economic development of distant regions is increasingly dependent on energy resources. This fact makes world scientific community pay more attention to renewable sources. Special paid solar, wind small hydropower for electrical consumers who have no possibility connect central power supply lines. that water resources financial support given mic...

Due to electricity market deregulation, the contribution of hydroelectric power plants to secondary control becomes of major interest regarding the electrical grid stability. Besides the grid stability improvements obtained with secondary control, the power utilities are more and more concerned by the influence of the constantly changing power set point on the lifetime of the power plant compon...

In a hydroelectric power plant or in a pumping station in order to avoid sudden large increase of pressure due to instantaneous valve closure sometimes a surge tank is installed. The height of surge tank is designed by the highest possible water level during the operation. The theoretical treatment of oscillation in a surge tank is difficult because of the non-linearity of friction term in the ...
