conditions. The corresponding subprojects are described in Fig. 2 and correspond to
following steps:
• Theoretical description of a single spherical particle settling in a gas flow under
laminar or turbulent conditions;
• Experimental investigation of fluid velocities, turbulent properties and vortex
structures in the ZAC;
• Numerical simulations of fluid velocities, turbulent properties and vortex structures in the ZAC;
• Experimental investigation of particle trajectories in the ZAC;
• Numerical simulation of particle trajectories in the ZAC (coupling Computational
Fluid Dynamics with either Discrete Particle Model—DPM—or Discrete Element
Model—DEM);
• Experimental investigations of separation based on particle size, particle density,
particle shape;
• Derivation of a simplified model of particle separation in the ZAC and integration
of this model into the central simulation platform DYSSOL developed in the group
of S. Heinrich at the Technical University Hamburg.
