blade angle has a significant effect on turbine efficiency. the HST with a twenty-one degree blade angle had 38.10% efficiency at the water flow rate of 2 m/s.
Evaluation of the Fluid Model Approach for the Sizing of Energy Storage in Wave-Wind Energy Systems. Analysis of the Potential for Use of Floating Photovoltaic Systems on Mine Pit Lakes: Case Study at the Ssangyong Open-Pit Limestone Mine in Korea. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. In this study, a Francis turbine with specific speed of 130 m-kW was designed on the basis of the port area and loss analysis. The results show that the effect of the port area of runner blade on the flow exit angle from runner passage is significant. In this study, a new method on basis of the port area and loss analysis to design a Francis turbine runner was developed for the Miryang power station in Korea. The meridional shape of the runner was designed on the basis of the combination of the guide vane loss analysis and experience.
### Study the Effect of Blade Angle on Hydrokinetic Turbine Performance. ***Abstract -*** *Harnessing renewable energy from water currents, such as rivers and tidal streams, without extensive infrastructure, positions hydrokinetic turbines as a highly promising technology. This research details the design and optimization of hydrokinetic turbine blade profiles to significantly improve their efficiency and overall performance. A comprehensive analysis, utilizing Computational Fluid Dynamics (CFD) simulations, was conducted to investigate the influence of varying angles on blade hydrodynamic performance. The findings conclusively demonstrate that the optimal selection of the blade angle can substantially enhance turbine efficiency, thus bolstering its potential for large-scale energy production. Furthermore, a specific angle of 67.5 degrees exhibited an unexpectedly superior power output compared to angles of 15 and 45 degrees. This work advances hydrokinetic technology and provides a robust framework for the continued optimization of renewable energy systems.*. ***Keywords:*** CFD, energy, hydrokinetic turbine, blade angle. The objective of this project is to design, build, and test a hydrokinetic turbine with different blade angles.
