Existing Francis turbine
Characteristics:
- power 16 MW
- speed min-1
- mass flow 11-17 m3/s
-geometry
- spiral cast Din = m
- runner Din/Dout = / m
- radial-axial runner
- number of blades
-stayring 10
-wicket gate 20
-runner 15

Goals
Try to increase turbine power with the
geometry modification of:
- stayring venes,
- guide vanes,
- runner blades
Tools
- Gambit
- Fluent
- optimisation package (ic Algorithm)
Francis turbine fluid flow simulation
1. preprocesing (Gambit)
2. calculating (Fluent)
3. postprocesing (Fluent & FluentPost)

For presentation purposes and better
visualization the next slides contain meshes
which are very corse (very bad y+).
This meshes are not using for calculations.
