Abstract

Simulations of urban environments can have substantial benefits to public safety. This can be in scenarios of danger assessment such as those related to the release of chemical and biological hazards. The currently used simple, semi-analytical models have trouble predicting realistic cases and hence require accurate aerodynamic simulations. LBM is used here since it produces high-fidelity simulations within a reasonable timescale. The LBM code is currently being developed based on the AMROC framework, which uses adaptive mesh refinement. Simulations have been conducted on cube configurations at various Reynolds numbers to simulate flow around buildings. The results show that the solver with adaptive mesh refinement can be used to efficiently solve atmospheric problems.
