Aggregates settle in viscous fluids in specific directions depending on their morphology. We investigated the settling behavior of fractal aggregates with D = 1.85 in fluids using the Accelerated Stokesian Dynamics method. The results have been compared with experimental data. A simple equation is proposed which gives the drag force in dependence on the radius of gyration r, the projection area A and the aggregate orientation during settling. This equation reproduces the data from ASD within ± 10 % for Re <1. Additionally, a new algorithm has been developed which allows a prediction of the orientation of such fractal aggregates provided that they have time enough to orient in the fluid. Moreover, the drag force acting on them can be predicted in a narrow range (maximum error 15%). This algorithm allows a very fast evaluation of the orienting behavior with small deviations. © 2008 Elsevier Inc. All rights reserved.
