Geo: solidworks Mesh: Turbogrid
Typically Features of wind turbine blades
- highly twisted
- no shroud.
So this cannot be meshed in TurboGrid.
- The best option is to use ICEM CFD Hexa to generate a grid for such blades.
- One way to overcome this is to split the blade near the tip, so that you put an artificial shroud.
This can then be mesh in TurboGrid. As for the tip section you can generate a mesh in ICEM CFD Hexa or tetra and use ggi‘s to connect the two meshes in CFX Pre.
Limits
the shroud must be defined near the tip of blade but in the wind turbine study we need a region between tip and shroud for this we cannot use turbogrid
- GGI option for shroud can be used and has been used by ppl to simulate wind turbines using turbo-grid meshing.
- For Blade Profile definition you just need the co-ordinates. i. e.
If you want to rotate a blade about x. axis, define the airfoils in X-Y planes and vary Z co-ordinate. I myself have done this and my blade was twisted as well.
- Cartesian co-ordinates are enough, no need to enter cylindrical co-ordinates.
