Abstract: Direct numerical simulation of nanoparticle coagulation in a two-dimensional mixing layer is performed. A sectional model is used to discretize the particulate field resulting in a set of coupled non-linear partial differential equations each representing the concentration of particles of a particular size. The advantage of this approach is that it provides a robust mathematical framework for considering the particulate field as a function of space, time, and size with no a priori assumptions. The spatio-temporal evolution of the particulate field is visualized via the mean particle diameter and also in a size-specific manner.
