Guidance in Gambit 2.4 -- How change airfoil chords in Wells turbine model?

In summary, the conversation is about the Wells turbine and the speaker's thesis on the subject. They are discussing a model made in Gambit 2.4 and the speaker wanting to make adjustments to the airfoil cord. They mention using the sweep tool but do not think it is efficient. They suggest using coordinates from two airfoils to create a new model and ask for recommendations for websites that provide different chord coordinates. The conversation ends with the speaker expressing gratitude for the help and mentioning a previous model with no satisfactory solution.

hi my dear friends,

Wells turbine is the subject of the my Thesis:

http://www.upload7.ir/imgs/2014-10/37346220310608280524.jpg
i make below model in gambit 2.4 ,But now I want to make the upper airfoil cord bigger than the bottom one.

below model is constant,attention to third pictures( Attend dash line)

Now Here,
I do not think the sweep tool is efficient(attention to below picture ).

I think that have the coordinates of the vertexes from the two airfoils(for blade),I can easily Create New model.

Do not know of a site that would provide the coordinates airfoils with different chord?

The following sites provides coordinates but I think cords are identical:

Another way you know, Guide me.thanks for your help.

Related to Guidance in Gambit 2.4 -- How change airfoil chords in Wells turbine model?

1. How do I change the airfoil chords in a Wells turbine model in Gambit 2.4?

In order to change the airfoil chords in a Wells turbine model in Gambit 2.4, you will need to access the "Edge" menu and select the "Scale Edge" option. From there, you can specify the amount by which you want to change the chord length.

2. Can I change the chord length of multiple airfoils at once in Gambit 2.4?

Yes, you can change the chord length of multiple airfoils at once in Gambit 2.4 by selecting all of the desired edges and using the "Scale Edge" option from the "Edge" menu.

3. What is the recommended method for changing airfoil chords in a Wells turbine model?

The recommended method for changing airfoil chords in a Wells turbine model is to use the "Scale Edge" option from the "Edge" menu in Gambit 2.4. This ensures that the changes are made consistently and accurately across all selected edges.

4. Can I undo changes to airfoil chords in Gambit 2.4?

Yes, you can undo changes to airfoil chords in Gambit 2.4 by using the "Undo" option from the "Edit" menu. This will revert any changes made to the selected edges.

5. How can I ensure that the changes to airfoil chords in my Wells turbine model are accurately reflected in my simulations?

In order to ensure that the changes to airfoil chords are accurately reflected in your simulations, it is important to verify the mesh and boundary conditions after making the changes. You may also want to perform a sensitivity analysis to determine the impact of the changes on your results.
