Application of CFD modelling to air quality in Kuwait City

Abstract

High-resolution computational fluid dynamics (CFD) simulations have been performed to assess the dispersion of air pollutants (CO 2 ) emanating from traffic in a busy street and in the vicinity of a complex configuration of buildings located in Salmiya, Kuwait City. New buildings are planned for this area, and the work here includes predictions for the dispersion of pollutants after the buildings' completion. The CFD simulations are based on calculated CO 2 concentration levels for traffic counts taken on location in Salmiya with the existing configuration of buildings. As the computer code used in this work has been evaluated previously, it will be applied here to predict with confidence any potential air pollution problem areas on the addition of the new buildings. It was found for very light wind, that the proposed new buildings help reduce pollution in the vicinity of residential buildings within the configuration of buildings, but as the wind becomes moderate to strong, there was a tendency for the pollutant to get trapped in the residential area. Results are given for both exceptionally high ambient temperatures and very light wind, which are not often reported in studies found in the literature.

“…In general, this motor vehicle is fueled by oil which is a producer of carbon monoxide gas in its combustion (Zong & Zhang, 2014;Dash et al, 2017;Morakinyo et al, 2016;Emanuel, 2017). Carbon monoxide gas is very harmful to the human body (Coudon et al, 2018;Gallagher & Lago, 2019;Iodice et al, 2017;Irwin et al, 2018;Moreira & dos Santos, 2019;Mylläri et al, 2016;Seto et al, 2014;Zhunussova et al, 2017). Monoxide gas produced by motorized vehicles at medium speeds is different from those at high speeds.…”
