The hydrodynamic radius Rh was calculated and compared with the radius of gyration Rg for a series of fractal aggregates to get an insight in to the role of the aggregate size and fractal dimension. We show that R ∼ N1 / Df and Rh / Rg = f (Df). In addition, a new characteristic radius Rβ has emerged from a scaling of numerical results. 3D fractal aggregates Lattice Boltzmann Hydrodynamics Dewey 025.063 Dewey 540 13 Centre universitaire d'informatique 0D3 40 Département de chimie minérale, analytique et appliquée 145 32 Département d'informatique 18 false 728 Scientific and Parallel Computing Mathematics and Computers in Simulation 72 2-6 640541d0-ff7f-450b-a442-61cc4e26d746 Article (Published version) Restricted 2006Chopard_lattice_bolz_hydrodyn.pdf 300147 application/pdf restrictedAccess Centres et instituts / Centre universitaire d'informatique Faculté des sciences / Section de chimie et biochimie / Département de chimie minérale, analytique et appliquée Faculté des sciences / Département d'informatique
