Zanke turbulent lift force

hi everybody
i am simulating what "Klemens Gruber" has done to model sediment bed load tranportation
(http://www.jku.at/itp/content/e61131/e111072/e112573/e196534/e196561)
i need to include a turbulent lift model named "Zanke" lift model (which is necessary for packed particles)
does anyone know whether CFDEM has such a turbulent lift force or not?
and if not , where can i find the code?
i myself wrote its code but it seems does not work well!
i appreciate any help
