Drag enhancement in a dusty Kolmogorov flow
A. Sozza, M. Cencini, S. Musacchio +1
Particles suspended in a fluid exert feedback forces that can significantly impact the flow, altering the turbulent drag and velocity fluctuations. We study flow modulation induced…

Scalar absorption by particles advected in a turbulent flow
A. Sozza, M. Cencini, F. De Lillo +1
We investigate the effects of turbulent fluctuations on the Lagrangian statistics of absorption of a scalar field by tracer particles, as a model for nutrient uptake by suspended n…

Accumulated densities of sedimenting particles in turbulent flows
Alessandro Sozza, Gabor Drotos, Emilio Hernández-García +1
We study the effect of turbulence on a sedimenting layer of particles by means of direct numerical simulations. A Lagrangian model in which particles are considered as tracers with…
