Numerical modeling and experimental investigation of fine particle coagulation and dispersion in dilute flows

In this work, a numerical model will be developed to study the behavior of fine and ultra fine particles under conditions typical for air pollution problems. The particles considered are much heavier than the surrounding fluid, and can have sizes ranging from 5 nm to 10 μm. E↵ects of inter-particle collisions and coagulation will be included in the model.
The current discussion focuses on the development of the solver for the incompressible Navier-Stokes equa- tions, using the SUPG finite element technique and with an implementation that makes use of a Domain Specific Embedded Language.
Finally, some preliminary PIV measurements, to be used for validation of the simulated flow field, will also be presented.
