Résumé

The jet fan system used in the ventilation of underground car parks is an efficient system. The Local Mean Age of air, LMA, is one of the most important parameters when the air quality in an enclosed car park is considered. No literature thus far on the LMA in underground car parks has been published for public use. This paper aims to give a comprehensive account of the importance of using the LMA concept in the design of such systems using CFD simulations. Five cases were examined; each case has a different amount of jet fans with different configurations. An underground car park was chosen for this investigation with a 94 m length, a 70 m width, and a 3.7 m height. The ANSYS FLUENT 14.0 software was used for all numerical results obtained. The fourth case gives a better result. It was found that the LMA gives good insight in the determination of the length of time contaminated air stays in different areas of the car park.
