             Aggregation and fragmentation processes 
                    in synthetic turbulent flow

We analyze the aggregation-fragmentation dynamics of inertial 
particles in a synthetic turbulent flow. This flow is able to 
reproduce some of the properties of homogeneous isotropic 
turbulence at the dissipative scale. We consider that aggregation 
events happen under particle collision, whether fragmentation 
occurs due to shear forces exerted on the particle by the flow 
field. We investigate how the time scales of the flow and of the 
aggregation/fragmentation events can influence the size 
distribution of aggregates at the steady state.
