Francis turbines play a major role in both small scale 
and large scale hydraulic energy plants and are 
increasingly being used for energy storage applications 
where pump/turbine arrangement is used to store energy 
from renewable sources such as wind and solar. The 3D 
inverse design method offers one of the best means of 
meeting multi point and multi-objective requirements for 
hydraulic turbines as it can cover a large design space 
with very small number of design parameters. This enables 
efficient multi-point optimization hydraulic turbines.

In this webinar we will show how the newly developed 
meanline design code for Francis turbine, which has been 
recently developed in TURBOdesign Suite, can be used to 
do the initial sizing of all components of a Francis 
turbine from volute, stay vane, guide vane and runner. We 
will demonstrate how the new meanline code coupled with 
TURBOdesign1 and TURBOdesign Volute can be used to 
quickly generate a complete 3D Francis Turbine stage that 
meet the main duty points of the stage and provide a high 
efficiency.

Furthermore, we will show how TURBOdesign1 with its 
direct control of blade loading or pressure jump across 
the blade 
provides the best means of directly controlling the 
efficiency and cavitation performance of the runner.
