Abstract

The objective of this study is to demonstrate the capability of an arbitrary mach number algorithm to predict aerosol propagation in an urban environment. A preconditioned approach¹ is applied to an unstructured mesh to determine accurately the highly unsteady turbulent How Held about the urban setting. DES modifications are implemented into a hybrid k - ∈, k - ω turbulence model² and evaluated. A scalar transport model is used to release and to advect the aerosol agent through the urban landscape. Comparisons between RANS and DES turbulence modeling are presented for multiple agent release scenarios.
