Local analysis of the clustering, velocities and accelerations of particles settling in turbulence
Mohammadreza Momenifar, Andrew D. Bragg
Using 3D Vorono\text{ï} analysis, we explore the local dynamics of small, settling, inertial particles in isotropic turbulence using Direct Numerical Simulations (DNS). We independ…

Is vortex stretching the main cause of the turbulent energy cascade?
Maurizio Carbone, Andrew D. Bragg
In three dimensional turbulence there is on average a cascade of kinetic energy from the largest to the smallest scales of the flow. While the dominant idea is that the cascade occ…

Multiscale preferential sweeping of particles settling in turbulence
Josin Tom, Andrew D Bragg
In a seminal article, \citet[J. Fluid Mech., 174:441-465]{maxey87} presented a theoretical analysis showing that enhanced particle settling speeds in turbulence occur through the p…
