Abstract
We present aggregation experiments in a bidimensional suspension of macroscopic spherical particles undergoing a shear. The aggregation is due to attractive capillary forces the value of which can be changed. We introduce a dimensionless quantity A expressing the relative importance of capillary forces and of the shear effect. We observe various aggregate configurations related to the values of A. In particular when the clusters show a fractal structure we find one Hausdorff dimension equal to 1.7 ± 0.05Keywords
