1. ANSYS BladeModeler 11.0 Practical 1
Axial Turbine Stator

2. Concepts
Starting BladeGen within WorkBench
Opening an existing design
Mouse functions and viewer options
Using BladeEditor to import model to DesignModeler
Discussion of different workflows based type of analysis to be performed

3. Axial Turbine Stator BladeGen file: Axial_Turbine_Stator.bgd
Conditions
Fluid: Air Ideal Gas
Inlet flow direction: normal to inlet
Inlet Pt: 445 [psia]
Inlet Tt: 783 [o F]
Exit Ps: 223 [psia]

4. The ANSYS Start Page Launch ANSYS BladeModeler:
Click ANSYS WorkBench icon
In Windows start ANSYS Workbench under
Start Menu > Programs > ANSYS 11.0
The Workbench-based products are no longer separate applications. Instead, Design Simulation, DesignModeler, and DesignXplorer are all launched from one “ANSYS Workbench” icon in the Start Menu. Workbench can also be accessed directly from supported CAD systems from an “ANSYS 7.1” pull-down menu, as shown in the middle. Lastly, Workbench can also be launched via the “ANSYS Classic” icon, which was previously known as the “ANSYS Interactive” icon. When launching ANSYS Classic, selecting the “ANSYS Workbench Environment” button on the bottom, as shown on the right, will launch Workbench instead of the classic Environment.

5. BladeGen in Workbench Launch BladeGen from the ANSYS start page
Click the Blade Geometry icon

6. BladeGen – Open Design
Open file > Axial_Turbine_Stator.bgd

7. BladeGen – Aux View Switch to 3D view using this icon
Use these icons to show one, two, or all blade sections
Show geometry as wireframe, meshed, and shaded
The Display Group Control Dialog determines which components are shown

8. BladeGen – Mouse commands
Common mouse commands – try manipulating the different views
We won’t make any modifications to this geometry

9. Export the geometry to TurboGrid for meshing (CFD analysis)
BladeModeler
Now that the geometry is complete, the next step in the analysis process could be:
Export the geometry to TurboGrid for meshing (CFD analysis)
Import the geometry into DesignModeler
Add features
Generate fluid domain for meshing in CFX-Mesh, ICEM (mesher other than TurboGrid for CFD analysis)
Generate solid model for Simulation (Finite Element Analysis)
Export blade geometry for prototyping

10. ANSYS BladeModeler Practical 1
Exporting TurboGrid curve files

11. Export to TurboGrid
If we are to use TurboGrid to mesh the blade, export the .curve files
Click the TurboGrid Export icon
Save the .curve files as shown below

12. ANSYS BladeModeler Practical 1
Importing Blade Geometry in to DesignModeler

13. BladeModeler – Project Page
Switch back to the project page
Click New geometry to Launch DesignModeler

14. DesignModeler
When prompted to select units, choose mm
Click the BladeEditor Icon to import the blade geometry

15. DesignModeler
By default, the design open in BladeGen is selected >
click Open

16. DesignModeler
The importBGD panel is activated
Change Hub Offset to 2
Click the Generate icon

17. DesignModeler Two Parts are created
Solid Body is created for FEA or CAD export
Fluid Zone for CFD simulation created

18. DesignModeler
Insert a fillet where the blade meets the hub
Right click on Fluid Body 1
Insert > Fixed Radius

19. DesignModeler
Select the 5 edges the make up the intersection of the main blade and hub surface on the blade surrounded by the fluid domain
Hold CTRL key to multi select

20. DesignModeler
Tip:
There are two tiny surfaces (one at the leading edge, one at the trailing edge)
Zoom in to select these

21. DesignModeler
Once all 5 edge have been selected, click Apply
Select 2mm for Radius

22. DesignModeler
Click Generate icon

23. DesignModeler
Note fillet is added to solid and fluid parts

24. DesignModeler
For a CFD simulation, we can suppress the solid body
Right click on the solid in the tree representing the turbine and click Suppress Body
This leaves the Fluid Body

25. Project Page – Next Steps
Select .inf file and open in TurboGrid to create a mesh for CFD OR
Select New Mesh to create a CFD mesh on the filleted blade geometry using CFX Mesh OR
Select New Simulation to perform a Finite Element Analysis
