Three groups of aggregates with fractal dimensions of 1.89 ( 0.06, 2.21 ( 0.06, and 2.47 ( 0.10 were generated by coagulation of latex microspheres (2.85 μm) in a Jartest (paddle-mixing) device. The collision rates between these fractal aggregates (200-1000 μm) and small (1.48 μm) particles were measured in the turbulent shear environment of the paddle mixer at mean shear rates of 2.1, 7.3, and 14.7 s-1. Collision frequencies were 5 orders of magnitude higher than predicted by a curvilinear… CONTINUE READING
