Abstract


The Hei River Hydropower is the third cascade hydropower stations in the upper reaches of Hanjiang River Reach Planning is one based power generation, comprehensive benefits for both shipping and other medium-sized hydropower hub . The flood energy dissipation is characterized by a narrow river , peak flow , tail water is high and the range is large , low discharge flow Fr reservoir regulation capacity is weak and low bedrock anti-erosion ability . For the the test validation engineering project layout and spillway energy dissipation feasibility , through the establishment of the project as a whole model for test process improvements and measures to meet the requirements of the operation of the project , the proposed optimization program . The main work of this paper include the following: expounded the advantages and disadvantages of the various forms of energy dissipation , and summary of the situation at home and abroad at this stage the development of the energy dissipation type . Describes the problems encountered by the hydraulic jump energy dissipator design discharge per unit width low Froude , and hydraulic jump energy dissipation characteristics of the discharge structure of this type and to solve the problems . Gravity similarity criterion according to the characteristics of the Hei River Hydropower Engineering discharge structure , determine the test purpose and mission , model design and production of the model , select the measurement instrument , the overall and sectional model test . In this project , table hole located differential Hom overall hydraulic model test . Determination of various inlet flow pattern , the chamber flow pattern , downstream flow convergence flow pattern, velocity distribution as well as downstream the reflux and tail water fluctuation condition . Determination of the various frequency flood
