Aerator of stepped chute in Murum Hydropower Station

Simulation Modeling for Electrical Switching System of Hydropower Station

This paper proposes a simulation modeling method for the electrical switching system of hydropower station, which is a sub-topic for Hydropower Station Simulation Training System. The graphics model of commonly used electrical switch equipment is developed with a certain software [1]. As vast and different types of Hydropower station circuit breakers and associated grounding switches, and each ...

Chaotic Optimal Operation of Hydropower Station with Ecology Consideration

Traditional optimal operation of hydropower station usually has two problems. One is that the optimal algorithm hasn’t high efficiency, and the other is that the optimal operation model pays little attention to ecology. And with the development of electric power market, the generated benefit is concerned instead of generated energy. Based on the analysis of time-varying electricity price policy...

Air–water flow properties in step cavity down a stepped chute

For the last three decades, the research into skimming flows down stepped chutes was driven by needs for better design guidelines. The skimming flow is characterised by some momentum transfer from the main stream to the recirculation zones in the shear layer developing downstream of each step edge. In the present study some physical modelling was conducted in a relatively large facility and det...

Micro- and Macro-scopic Study of Two-phase Flow on a Stepped Chute

Stepped chute flows are characterised by intense turbulence and strong flow aeration (Fig. 1), but most studies did not investigate the turbulence characteristics. Detailed air-water flow properties were measured in skimming flow on a stepped chute (θ = 16o, h = 0.05 m). Longitudinal oscillations of depth-averaged flow properties were observed with a wave length of about two step cavity lengths...
