Modeling Scalar Dispersion in Urban Environments

	David Philips Undergraduate Institution: Thayer School of Engineering, Dartmouth College

The study of scalar dispersion in turbulent flows is relevant to a range of applications including the investigation of hazardous releases and control of air quality in urban environments. Accurately modeling a release event involves taking into account a range of scales from global weather patterns, to wind incident on a city, to flow around a single building.

We aim to perform credible and accurate simulations of release scenarios in urban environments. Our approach to obtaining this goal is two-fold. First, we are developing the tools to run full scale simulations of scalar dispersion in urban environments using an Oklahoma City validation case. Second, we are evaluating the performance of existing scalar transport models in complex geometries like a 3D, wall-mounted cube.
