# Design and Analysis of Francis Turbine. ## Uploaded by. AI-enhanced title and description. This document provides details about the design and analysis of a 40 MW vertical Francis turbine with a head of 65 m and flow rate of 70.10 m3/s. It includes the design parameters calculated for the turbine runner such as diameter, height, and blade angles. It also discusses the selection of turbine type based on head and flow rate. The main components of a Francis turbine and the design theory are described. Equations for calculating turbine power and efficiency are provided, assuming negligible friction and infinite guide vanes. ## Share this document. ## Footer menu. ## Support. ## Legal. ## Social. ## Get our free apps.

# Francis Turbine Design for Hydropower Generation. Home » Francis Turbine Design for Hydropower Generation. CFTurbo Francis Turbine Design for Hydropower Generation. As the world shifts to greater reliance on sustainable energy sources, the design and optimization of relevant turbomachinery devices are imperative. The CFturbo software allows its users to build and optimize all components of Hydro Turbines, as shown in this introductory case study of a Francis turbine. The Francis turbine is a longstanding monument in the world of turbomachinery, dating back to the mid-19th century. The Francis turbine was invented in the mid-19th century by engineer James Bichens Francis to produce hydroelectric power. A baseline geometry was prepared using the Hydro Turbine module within the CFturbo software. Figure 2 Francis Turbine Design – CFturbo, 3D View. Using a CFturbo engineered Python script solution in conjunction with the Replace Part Operation within Star-CCM+, 25 unique Francis Turbine CFturbo designs were created and simulated using a mesh of approximately 8.5 million polyhedral cells and a steady-state solver.

# 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.

# 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.
