Outline of Final Research Achievements

Seeking a new interdisciplinary-plane supported by two columns; statistical physics and urban climatology, we established a brand-new simulation technology combining Multi Agent Simulation; MAS and Computational Fluid Dynamics; CFD. Our new simulation model aims precise predictions and evaluation of air-pollutant diffusion in any urban canopy context considering that a moving vehicle in an urban street significantly affects on scalar dispersion due to its production of mechanical sheer in terms of turbulent mixing effect. The model dovetails Revised S-NFS model, one of the Cellular Automaton models, enabling likely motions of a vehicle showing various stochastic features, with Large Eddy Simulation (LES), one of CFDs that is able to accurate time evolution of aerodynamics flow fields.
