Brownian dynamics simulations is a simulation technique especially designed for colloids. The degrees of freedom of the solvent are integrated and the motion of Brownian particles can be described in a 'realistic' way. This technique has been used for studies in colloidal hydrodynamics, aggregation, phase transitions, rheological behaviour of colloidal glasses... In this seminar, I will present results concerning colloidal aggregation under long-range interactions. The aggregation kinetics (both short and long time) will be studied, as well as the structure of the clusters formed in the late stages of aggregation. Repulsive and attractive forces will be considered, and the results will be compared with experiments, showing good agreement.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
