Discrepency in Corey Relative Permeability Correlation

[Ethan]

I noticed that the in the dialog box for "Additional Material Data -> Relative Perm", the displayed functional form of the Corey Curve correlation is inconsistent with the TOUGH2 Manual. The function displayed in the dialog box is as follows:

RPgas = ((1-S)^2 * (1-S)^2)

where S = (Sl - Slr)/(1 - Slr - Sgr)

However, according to the TOUGH2 manual, the functional form should be the following:

RPgas = ((1-S)^2 * (1-S^2))

I would imagine that the code is actually correct and that the displayed formula in the dialog box needs to be amended.

Hope this helps,

Ethan

Yes, you are correct. The TOUGH2 source code matches the form:

RPgas = ((1-S)^2 * (1-S^2))

I've added a note to our bug tracker.
