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.

# Francis turbine. Francis inlet scroll at the Grand Coulee Dam. Side-view cutaway of a vertical Francis turbine. Here water enters horizontally in a spiral-shaped pipe (spiral case) wrapped around the outside of the turbine's rotating *runner* and exits vertically down through the center of the turbine. The **Francis turbine** is a type of water turbine. Francis turbines are the most common water turbine in use, and can achieve over 95% efficiency. A wicket gate "Wicket gate (hydraulics)") around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for different power production rates. Francis turbines are usually mounted with a vertical shaft, to isolate water from the generator. The Francis turbine is a type of reaction turbine, a category of turbine in which the working fluid comes to the turbine under immense pressure and the energy is extracted by the turbine blades from the working fluid.

In the reaction turbines, only some part of the available total head of the fluid is converted into kinetic energy so that the fluid entering the runner has pressure energy as well as kinetic energy.

# Design of a Francis Turbine Stage. Over the years, ADT has helped many major customers streamline and speed up the design and optimization of Francis turbine stages, and has developed considerable fluid dynamic knowledge to design high-performance Francis turbines in the process systematically. The first step in the design of any hydraulic turbine is to identify the required specific speed regime of the turbine. **Meanline Design of Francis Turbine Stage**. Figure 1 contains the stage specifications, consisting of a volute, stay vanes, guide vanes, runner and a draft tube. Figure 2: Meanline design of Francis turbine stage in TURBOdesign Pre. Figure 3 presents the setup for the baseline Francis turbine stage in our 3D inverse design software TURBOdesign1, and these axial chord distributions for the stay vane, guide vane and runner, they all come from the meanline code as we saw earlier.
