Simulations of dispersion through an irregular urban building array

ATMOSPHERIC ENVIRONMENT, 258.

By: M. Pirhalla n, D. Heist *, S. Perry *, W. Tang * & L. Brouwer*

author keywords: Urban dispersion; Wind tunnel; ELES model; Gaussian plume model; Emergency response; Jack Rabbit II
TL;DR: This project leverages the configuration of buildings used in a full-scale, mock urban field study to examine the concentrations of a neutrally buoyant tracer in a series of wind tunnel and Embedded Large Eddy Simulation (ELES) experiments and shows that a nonlinear least squares fit of the Gaussian plume equation well represents these profiles, even within the array of buildings and network of street canyons.

Urban wind field analysis from the Jack Rabbit II Special Sonic Anemometer Study

ATMOSPHERIC ENVIRONMENT, 243.

By: M. Pirhalla n, D. Heist *, S. Perry *, S. Hanna, T. Mazzola*, S. Arya n, V. Aneja n 

Contributors: M. Pirhalla n, D. Heist *, S. Perry *, S. Hanna, T. Mazzola*, S. Arya n, V. Aneja n 

author keywords: Jack rabbit II; Turbulence; Microscale meteorology; Sonic anemometry; Urban dispersion; Building wakes
TL;DR: It is shown that the flow within the building array follows a tendency towards one of three generalized flow regimes displaying channeling over a wide range of wind speeds, directions, and stabilities, which can be used to inform the development of improved wind flow algorithms to better characterize pollutant dispersion in fast-response models.
