Abstract

The evolution of the particle size in turbulent particle-laden flows is a complex phenomenon, which plays an important role in various environmental (e.g., air pollution) and industrial applications (e.g., dry powder inhalers). The main challenge for investigating such flows is the extensive range of length and time scales to be dealt with, especially in the case of turbulent flows.
