# Francis turbine blade design on the basis of port area and loss analysis. 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 meridional shape of the runner was designed focusing mainly on the combination of the guide vane loss analysis and experience. The runner blade inlet and outlet angles were designed by calculation of Euler's head, while the port area of blade was modified by keeping constant angles of the blade at inlet and outlet. The results show that the effect of the port area of runner blade on the flow exit angle from runner passage is significant. A correct flow exit angle reduces the energy loss at the draft tube, thereby improving the efficiency of the turbine. The best efficiency of 92.6% is achieved by this method, which is also similar to the design conditions by the one dimension loss analysis.

# How Does Pitch Angle Control Improve Wind Turbine Efficiency? However, the efficiency of these turbines can vary significantly depending on several factors, including wind speed, turbine design, and, importantly, pitch angle control. Understanding how pitch angle control improves wind turbine efficiency provides insights into optimizing renewable energy resources. Pitch angle control refers to the adjustment of the angle at which wind turbine blades meet the wind. This mechanism is crucial for regulating the rotation speed of the turbine and ensuring it operates at optimal efficiency across varying wind conditions. By adjusting the pitch angle, the blades can capture the maximum possible energy from the wind while minimizing wear and tear on the turbine components. 1. \*\*Active Pitch Control:\*\* In this system, each blade's angle is adjusted individually and continuously, allowing precise control over the rotor speed and power output. 1. \*\*Enhanced Efficiency:\*\* By optimizing the angle of the blades, pitch angle control ensures that the wind turbine operates efficiently across a wide range of wind speeds.
