Abstract
The present research shows the effect of air distribution systems by fixed location of air inlet at the ceiling of train cabin and different locations and dimensions of air outlets in six different cases and compared with them to reach the best result of the thermal comfort. The present numerical study was done by using ANSYS fluent 15 CFD (computational fluid dynamics) package. Techniques species transport as well as RNG k-epsilon model equations for turbulence model. Mesh sizes used in the present study were about 7,000,000 mesh volumes and 1,000 iterations for each case
