I want to say that the criterion of airfoil selection is according to this reference [72]. So, Is the use of "is based on" in the following sentences correct grammatically and conceptually? If it is not , kindly suggest ways to make it clearer.

Therefore, in the present work, the criterion of airfoil selection at the tip section (NACA0020) for the VTB Wells turbine design is based on this reference [72].

  • Could you expand on according to? As used it seems to indicate a vague relationship.

When describing criteria, use for. Using is based on is correct.

Therefore, in the present work, the criterion for airfoil selection at the tip section (NACA0020), used in the VTB Wells turbine design, is based on this reference [72].

I added used in to avoid using for multiple times. After all, we're still describing the criterion: it's used in the design.

No, it just means that "this reference [72]." had some historical value in the current product.

For example, if the Boeing 747 was designed by making improvements on the Boeing 707, then you could say:

The design of the Boeing 747 was based on design of the Boeing 707.

They are obviously not the same or very similar.
