Description

The computational model for simulating particle motions in turbulent flows was further developed and used to analyze the transport and dispersion of particles in a recirculating flow region. The model for resuspension of particles from surfaces in a gas flow is also further developed; it accounts for the surface adhesion as well as hydrodynamic forces and torques. It includes effects of the structure of near wall turbulent flows as well as surface roughness. In addition, a direct numerical simulation procedure for analyzing the particle removal process in turbulent gas flows is also developed. The sublayer model for evaluating the particle ... continued below

The model for resuspension of particles from surfaces in a gas flow is also further developed; it accounts for the surface adhesion as well as hydrodynamic forces and torques. It includes effects of the structure of near wall turbulent flows as well as surface roughness. In addition, a direct numerical simulation procedure for analyzing the particle removal process in turbulent gas flows is also developed. The sublayer model for evaluating the particle deposition in turbulent flows is being extended to include the effect of particle rebound. Further progress was also made in the experimental study of glass fiber transport and deposition in the aerosol wind tunnel.
