Abstract: Adequate ventilation of enclosed parking areas is required to ensure the concentration of vehicle exhaust pollutants, especially CO so that the concentration do not reach the level, high enough to threaten the safety of the car park occupants. So an attempt has been made to observe the maximum amount of CO Ventilation for three different velocities of exhaust fans. The simulation of the whole setup is done using Computational fluid dynamics (CFD) via the software ANSYS. With the development of CFD tools, car park ventilation can be shifted from code-based approach to performance based approach, and then using CFD methods the authenticity of the proposed design is confirmed. The proposed underground parking is a trapezoidal type area with dimensions are of 35m and 25m non parallel sides, 35.35m parallel sides and height 4 m. Here in the model two inlets and two outlet is considered. The modeling shows the CO concentration variation considerably with no fans and different positions of jet fans. So using the results showing the level of CO dispersion for the 3 observed cases of jet fan positions, a comparative analysis is concluded for CO concentration within the parking area. A considerable improvement of CO concentration has been observed after using Jet fans in arrangement 3.
