Abstract:

The provision of an efficient and accurate Computational Fluid Dynamics CFD solver for simulating flows within an urban complex on the microscale with characteristic length scale extending to about1-2 km is required to support the development of an advanced atmospheric transport and diffusion multiscale modeling system for hazard assessment of chemical, biological, radiological or nuclearCBRN agents released within cities. The ultimate goal of this supporting effort is to construct a virtual test facility VTF that could eventually be used to develop guidelines and procedures for operating in the urban complex after a CBRN incident.
