Parametric Turbine model with OpenFOAM+cfMesh case ready to run

I’ve made a parametric turbine case avaliable. Thank’s to my company Minesto for letting me do that.

I’ve done a parametric turbine using Ruby scripting language,
Have set up script for running the entire simulation using cfMesh for volume meshing, OpenFOAM for simulating fields. Openscad for watertunnel-geometry.

geometry simulation

The turbine geometry has pitch as input parameter, you can easily modify to suit your needs.

The simulation has watertunnel size as input parameter.

It’s a steady state MRF model and it runs in 5-10 minutes on a i7-processor. Refine to suit your needs…

 

Case:
turbine_model_bjorn_bergqvist_minesto_ab.tar

Readme file:

Author to this method is Bjorn Bergqvist. Please refer to me or communicate if
you use the turbine geometry model in your work.

Prerequisites:
OpenFOAM 2.?.? (used by 3_run_simulation.sh)
cfMesh (used by 2_create_volume_mesh.sh)
OpenSCAD (used by 2_create_volume_mesh.sh, tunnelfactor 1 is already
generated)
Ruby 2 with spliner gem (for splined pitch, otherwise any Ruby will do)
   (install with: "gem install spliner")

Description of files and directories:
Allrun
   Run through script 1_ to 3_

1_create_geometry.sh
   Not necessary to run. Turbine geometry with pitchmod=0 is
   already generated in geom/turbine.stl.
   Usage: ./1_create_geometry <pitchmod>
   were <pitchmod> is modification of turbine blade pich
   if you are unsure: use pitchmod=0

2_create_volume_mesh.sh
   Usage: ./1_create_volume_mesh.sh <tunnelfactor>
   where <tunnelfactor> is the size of the tunnel where the turbine is simulated
   if you are unsure: use tunnelfactor=1

3_run_simulation.sh
   Usage: ./3_run_simulation.sh <tunnelfactor>
   will run on 4 cpus
   (change in decomposeParDict and 3_run_simulation.sh for other cpu count)

post_moment_table.sh
   Averages moments and forces from 990 to 1000 iterations.

Allclean
   Removes generated mesh and simulation.

turbine_geometry
   The Bjorn Bergqvist(C) turbine geometry.

cfMesh.template
   Directory with files used by cfMesh.

simpleFoam.template
   Directory for simulation (steady state, MRF)
