Summary0000721: PIlchErdman breakup
DescriptionThere's a mistake in the Pilch Erdman breakup model according to this old post
http://www.cfd-online.com/Forums/openfoam/91795-bug-pilcherdman-breakup-model.html
Steps To ReproduceThe mistake is in this segment.
 
       scalar Vd = Urmag*rho12*(B1_*taubBar * B2_*taubBar*taubBar);
        scalar Vd1 = sqr(1.0 - Vd/Urmag);
        Vd1 = max(Vd1, SMALL);
        scalar Ds = 2.0*Wec*sigma*Vd1/(Vd1*rhoc*sqr(Urmag));
Additional InformationReplace * with +
       scalar Vd = Urmag*rho12*(B1_*taubBar + B2_*taubBar*taubBar);

and remove the Vd1 from the nominator
      scalar Ds = 2.0*Wec*sigma/(Vd1*rhoc*sqr(Urmag));
