In this study, we performed a sensitivity analysis of external air pollutant sampling locations by using computational fluid dynamics(CFD) in determining the difference in pollutant levels between the exterior and interior of a vehicle. To assess the extent to which pollutants from the outside environment enter the vehicle’s interior, it is crucial to measure the air quality inside and outside the vehicle simultaneously. Typically, an external air sampling nozzle is installed on the vehicle’s exterior for sampling in driving conditions; however, this measure often leads to vehicle damage, making experimental sensitivity testing challenging. In this study, sampling locations were selected by considering environmental factors that could affect air quality sampling, such as the vehicle’s orientation(front/side), intake nozzle length, and turbulence caused by side mirrors. A flow analysis was conducted at each sampling location, and the mass fraction of NO₂ accumulated at each point over time was measured and compared. Based on these results, we proposed an optimal sampling location for external air pollutants after considering aerodynamic factors.
