A Francis turbine is mostly used in a hydropower plant due to the great efficiency compared to other turbines such as the Pelton and the Kaplan turbine. It works under a medium head (50 m to 300 m) and is handling a medium quantity of the water. The blade is the most critical part of the turbine, it must withstand high pressure from the

Considering the sustainability of micro-hydro power plants, the components of Francis turbine need some simplifications so that the manufacturing and

suitable for Francis turbines. However, all those micro hydro were using Cross-Flow and Pelton turbines with very less e ciency [10]. Not being able to manufacture the compatible Francis turbines, Nepalese micro hydro developers and turbine manufacturers are installing Cross ow turbines, which are being operated at very less e ciency.

In this paper, the performance analysis of two different Francis runners, manufactured using local technology of investment casting and pressing-welding method, was conducted. For making the manufacturing, installation and, operations of the turbine as simple as possible, the trapezoidal spiral casing with fixed guide vanes was implemented.

Siendo la turbina Francis una de las turbinas de mayor difusión en las grandes centrales hidroeléctricas, se plantea el diseño de una turbina Francis para una micro-central hidroeléctrica

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 is an

Our Francis turbines are commonly used at hydraulic head range of 5-300 meters. For Francis type turbine, water enters runner radially, and leaves axially. Francis type turbine is divided into vertical type and horizontal type. In general, vertical type is often used in micro water power station.

The Francis turbine is a type of water turbine that is widely used for generating hydroelectric power. It was developed by James B. Francis in the mid-19th century and is named after him. The Francis turbine is a reaction turbine, which means that it operates by the principle of fluid pressure and flow. It consists of a runner with
