Abstract: The flow and pollutant dispersion in urban street canyons are investigated using a two-dimensional numerical model with the k?ε turbulent closure scheme. It is shown that the flow field is characterized mainly by the number ...

Abstract: This study investigates thermal effects on the flow and pollutant dispersion in urban street canyons. A two-dimensional numerical model with a k?? turbulent closure scheme is developed, and the heat transfer between the ...

Abstract: Flow and pollutant dispersion in a densely built-up area of Seoul, Korea, are numerically examined using a computational fluid dynamics (CFD) model coupled to a mesoscale model [fifth-generation Pennsylvania State ...

Abstract: A three-dimensional computational fluid dynamics (CFD) model is developed to simulate urban flow and dispersion, to understand fluid dynamical processes therein, and to provide practical solutions to some emerging problems ...

Abstract: A circulating water channel is constructed to examine urban street-canyon flow. In the cases of an even-notch street canyon in which model buildings on both sides of the street have equal heights, one vortex is observed ...
