High Resolution Modeling of Atmospheric Releases Around Buildings

摘要

The application of Computational Fluid Dynamics (CFD) to the understanding of urban wind flow and dispersion processes has gained increasing attention over recent years. While many of the simpler dispersion models are based on a set of prescribed meteorology to calculate dispersion, the CFD approach has the ability of coupling the wind field to dispersion processes. This has distinct advantages when very detailed results are required, such as for the case where the releases occur around buildings andwithin urban areas. CFD also has great flexibility as a testbed for turbulence models, which has important implications for atmospheric dispersion problems.
