# How to Optimize a Francis Turbine Design with CFD. BlogMachinery & Industrial EquipmentHow to Optimize a Francis Turbine Design with CFD. A water turbine, with the Kaplan, Pelton, and Francis turbines being the most common ones, is a large rotary machine that works to convert kinetic and potential energy into hydroelectricity. These modern equivalents of the water wheel have been used for over 135 years for industrial power generation, and more recently hydropower energy generation. ## Francis Turbine **What Are Water Turbines Used for Today?**. Low-head hydropower systems are larger, as the water turbine has to be large to achieve a high flow rate while low water pressure is applied across the blades. These turbines are known as axial flow reaction turbines, as they change the pressure of the water as it flows through it. ## Francis Turbine **How Can You Optimize Your Water Turbine Design with CFD?**.

# 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.

# Understanding the Flow Through Francis Turbines. This is the first article in a 4-Part series on **Hydraulic Turbines:**. There are many types of hydraulic turbines; the most common ones are – Pelton turbines, Francis turbines and Kaplan turbines. Though all three types of turbines are designed to meet the objective of power extraction from water, they differ in their working mechanism and operating conditions. This article is the first in a series of articles on **Hydraulic Turbines**, covering various aspects like the difference between Pelton-Francis-Kaplan turbines, the working mechanism, and flow disturbances in Francis turbines. Turbine types - pelton turbine, Francis turbine, Kaplan turbine. ***Figure 2:** **a.** Pelton turbine. Another difference is that Pelton turbines are suitable for places with water stored at high altitude, which enables to attain high head and high velocity, while Kaplan turbines are better suited for locations with high water flow rate and low head. #### **The Working Mechanism of a Francis Turbine**.
