Abstract
Egypt expands in updating the old metro cars by new conditioned metro cars to achieve best thermal comfort of passengers inside the vehicle. Using FLUENT (ANSYS 16), the best temperature and flow distributions for both seated and standing people inside the metro car are obtained when air incident by angle 75o (case 2) with respect to horizontal axis giving acceptable results with respect to rolling stocks European standards EN 14750-1:2006 and it gives the best thermal comfort for both seated and standing people based on PMV model even with high PMV value from 1 to 2.5 which gives best thermal comfort when distribute the same number of inlet air vents as a modified model with PMV from 0.6 to 1.5
