Abstract

Numerical simulation of dispersion and deposition of aerosol particles in a channel flow over two square cylinders in tandem are performed. A Lagrangian particle tracking computational procedure is developed and is used to simulate particles transport and deposition. Drag, gravity, and buoyancy forces are included in the computational model. Ensembles of particles in asterisk arrangement are released from different source points to calculate their capture efficiency on walls and obstructions. The effects of source point location, gravity direction, size and density of released particles and the gap between obstructions on capture efficiency are discussed. Time evolution of dispersion of four different clusters of particles representing the worst possible situation, issuing from maximum obstruction capture efficiency, are also illustrated.
