Development of local-scale high-resolution atmospheric dispersion model using Large-Eddy Simulation, 2; Turbulent flow and plume dispersion around a cubical building

Nakayama, Hiromasa; Nagai, Haruyasu

In this study, we extended the local-scale high-resolution Large-Eddy Simulation (LES) model proposed in Part 1 of this paper and applied it to a simulation of turbulent flow and plume dispersion around a cubical building and investigated the basic performance of the LES model in comparison with the previous experimental data. As a result, the main characteristics of turbulence structures and dispersion behavior agreed well with those of the previous wind tunnel experiment. It is considered that the complex behaviors of turbulent flow and plume dispersion in the near-wake region of a cubic building are successfully simulated using the present LES model.
