摘要: Numerical and experimental analyses were applied to carbon monoxide (CO) concentration dispersion monitor air quality in an enclosed residential complex parking area Tehran. Firstly, the was preliminary assessed through verifying characteristics of problem including geometry boundary conditions. Then, proportion vehicular exhaust emissions estimated eventually numerical performed. In order perform calculation, a three-dimensional model created numerically simulate by FLUENT software that solves flow governing equations with finite volume method. FLUENT, species selected assess CO domain. analysis, measured using sampling bags 10 l 4 min at 6 different points. The sample drawn into electric pumps. findings show maximum amount is above permissible standard recommended World Health Organization. Pollutant accumulation significant confined areas. place where openings exist, level lower than other obtained from simulation are complete accord results.
