Inertial Particle Behaviour in Turbulent Fluid Flow

The influence of particle inertia, shape and orientation, and fluid turbulence intensity on the behaviour of particles in a channel flow is investigated using large eddy simulation coupled to a Lagrangian particle tracking technique that solves the Newton-Euler equations of rigid particle motion. The statistical moments of the particle velocity, the probability density function of the hydrodynamic acceleration and particle distributions within the flows are all used to characterise the particle-turbulence ...
