His name was "van der Waals".  If one wanted to use the possessive,
one would refer to "van der Waals' parameters", or, in England,
"van der Waals's parameters", but certainly not "van der Waal's
parameters".

Should the possessive be used?  Probably not.  Looking through
the index of Levine's "Physical Chemistry", I see "van der Waals
equation", "van der Waals force", etc., etc.  However, we also
have "Stokes' law" and "Trouton's rule", so a case can be made
for the possessive, I suppose.

A case can also be made for "van-der-Waals parameters" (by
analogy to "The New-York Historical Society", (complex noun
serving as an adjective) but this would probably be deemed
pedantic.  Then again, you do have a .edu address....
