“…is the square of propagation velocity and water flow directional speed specific value of surface turbulence at the critical fracture surface. The flow is race if the specific value is smaller than 1, critical flow if it equals to 1 and slow flow if it is bigger than 1. t r and 0 R are calculated jointly by equations (3) to (9).…”

Flood discharge and energy dissipation of large-scale hydraulic and hydroelectric projects are two key technological issues in project planning, design and construction phases. Hydraulic characteristics research of new type high dam flood discharge and energy dissipation facility is one of the major research directions of high-speed hydraulic. To deal with problems of flood discharge and energy dissipation faced in large-scale hydraulic and hydroelectric projects development such as high dam, large discharge and narrow river valley and so on, this paper proposes a new internal rotational flow shaft spillway which suits high arch dam and analyzes the design criteria and size of each part. Discharge volume and ratio of energy dissipation verifications are conducted to the designed internal rotational flow shaft spillway through physical modeling test. Results show that this new discharge and dissipation facility has simple structure; stable discharge volume with good discharge capacity, high ratio of energy dissipation and its project investment is low. Besides, this paper also analyzes the discharge performance of this new discharge and dissipation facility and proposed its discharge function relational expression based on modeling test results. This project research can offer theoretical basi s to further body optimization and engineering application of discharge and dissipation facility.

One of the important issues is the assessment of the strength of the elements of hydraulic structures, spillway structures, reservoirs, and hydraulic complexes, the determination of the connection mode of the basins, and the reduction of kinetic energy in the reinforced fields of the downstream pool. In this regard, it is especially important to determine the hydrodynamic characteristics of the flow of water moving in the apron and risberme area, which provides the stability of the downstream pool - the areas that indicate the distribution and direction of velocity and pressure.
