Study on the Reconstruction of Diversion Tunnel intoPressure Sudden Enlargement Release Tunnel

工程科学与技术, 2008
:High head ogee spillway is the most usual way for medium or low head hydropower stations to reconstruct the spillway tunnel. Due to the condition limitation of the topography and geology, some stations cannot employ in this way. A new way to reconstruct

Numerical modeling of OGEE spillway and comparing with physical results

, 2020
This study investigates the simulation of flow characteristics such as flow rate, water surfaces profile, and pressures distribution over ogee type spillway surface. Distribution of vertical velocity, pressure and shear stress in seven points on the surface of the spillway is simulated by using the FLOW-3D software based physical models obtained from ...

Design of the optimum ogee spillway toe for a maximum energy dissipation

, 2020
Hydraulic design of a spillway has been one of the most studied subjects in hydraulic engineering. Properly designed, flow condition dependent spillways will be able to release water efficiently and safely from a dam reservoir to the downstream. This study aims to investigate the energy dissipation at the toe of ogee spillway by making an ogee spillway

Experimental study about the local scour downstream of ogee spillway

, 2020
The local scour formed in the bed of rivers because of the water action is a common phenomenon, and by the time became an important topic to study while designing and operating hydraulic structures. Because of the complexity of the topic, no specific methodology was developed to certainly predict the scour development profile, but the majority of the ...
