| Research Abstract |
Our objective is to propose an approach to predict local-scale atmospheric dispersion behaviors by coupling between numerical weather prediction (NWP) and large-eddy simulation (LES) based computational fluid dynamics (CFD) models. We validated the basic performance of our model by comparing to the wind tunnel experimental data of turbulent flows and plume dispersion in building arrays, and the observed data over the central city area of Tokyo. From the above-mentioned, it is concluded that our approach is applicable to the problems of urban dispersion by accidental and intentional release of hazardous materials and nuclear disasters.
