FIG. 16.

Contaminant particle distribution during the dynamic equilibrium phase. (a) shows a snapshot of 3D contaminant particle distribution at t = 46.6 min. Red color in (a) marks buildings taller than 170 m. Particles in (a) are colored according to velocity magnitude. (b) depicts contaminant particles and their concentrations (in logarithmic scale) averaged over the dynamic equilibrium phase, on a horizontal plane 2 m above the mean ground level. The flow is from South (left) to North (right).
