CFD analysis of ventilation effectiveness in a public transport interchange

For that study a CFD steady state computational model of a public transport interchange (PTI) in Hong Kong has been used for the investigation and prediction of the typical pollutant emission pattern for buses. The effectiveness of displacement ventilation (DV) scheme often used for PTI, for the removal of pollutants, has been investigated with the numerical simulation. An alternative model is then proposed with a different location of supply and exhausts to improve thermal comfort and IAQ.
