Article by Feng, 2007, about particle transport with LBM and DEM

Hello,
has anybody implemented the algorithm propose by Ladd, Han, Owen in the paper “Coupled lattice Boltzmann method and discrete element modelling of particle transport in turbulent fluid flows: Computational issues “, 2007 available here: Feng2007 ?

I am having some problems with results and I would like to compare with somebody,
Thanks!
