Parametrisation in Dissipative Particle Dynamics: Applications in Complex Fluids

A brief overview of mesoscopic modelling for neutral and electrostatically charged complex fluids via Dissipative Particle Dynamics (DPD) is presented, with emphasis on the appropriate parametrisation and how to calculate the relevant parameters for given realistic systems. DPD is a technique that consists of carrying out a coarse-graining of the microscopic degrees of freedom and it is highly dependent on parameters describing the different kinds of force fields and the parametrisation. For this reason, we present here a revision of DPD parametrisation together with applications and comparisons with experimental results. The dependence on concentration and temperature of the interaction parameters for electrostatic and non-electrostatic systems is also considered, as well as some applications in complex fluids.
