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 ultrafine 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. Effects of inter-particle collisions and coagulation will be included in the model.
For the fluid model, the Finite Element Method implemented in COOLFluiD will be used [1], with LES for turbulence modeling. The particle model will use either an Eulerian approach, based on kinetic particle PDF equations, or a Lagrangian approach.
During model development, validation will happen using small-scale experiments and literature data. In a final phase, the developed model will be tested in two industrial problems.
