Simulation of simplified urban flows using Lattice Boltzmann Method
Simulation of simplified urban flows using Lattice Boltzmann Method
Simulations of urban environments can have substantial benefits to public safety. This can be in scenarios of hazard assessment such as those related to the release of chemical and biological hazards. The current simple models have trouble predicting realistic cases which require accurate aerodynamic simulations. LBM is used since it produces high-fidelity simulations within a reasonable timescale for hazard assessments. The LBM code is currently being developed on the AMROC framework which uses adaptive mesh refinement. Cases have been conducted on cubes at various Reynolds numbers and configurations to simulate flow around buildings. The results show the solver with adaptive mesh refinement can be used to efficiently solve atmospheric problems.

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