Part of the Notes on Numerical Fluid Mechanics and Multidisciplinary Design book series (NNFM, volume 110)


Preferential concentration of solid inertial colliding particles suspended in homogeneous isotropic turbulence is numerically investigated using Direct Numerical Simulation (DNS) coupled with Discrete Particle Simulation (DPS). The results show that the preferential concentration is decreasing when the collision frequency increases. This effect is found enhanced for non-elastic particle-particle collisions.
