COMPARATIVE ANALYSES OF AIR FLOW REGIMES AND THERMAL PATTERNS IN PASSENGERS TRAIN CABINS
To reach the thermal comfort required in addition to the safety environment and conditions for the travelers.We must study many researches to reach the best thermal comfort case to can avoid any possibility of the occurrence or the spread of an infection inside the trains cabins such that this diseases occur due to the near distance between the passengers bodies with each other in addition to the long distances of the travelling such as the SARS,coronavirus and other diseases can form inside the trains due to existence many contaminated gases like Carbon dioxide,Organic volatile compounds and other gases.The present research shows the effect of air flow regimes and thermal patterns in train cabins by fixed location of air inlet at the ceiling and different locations of air outlets inside the train cabin and compared with each other to reach the best result of the thermal comfort.The present numerical investigation 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 studying were about 7,000,000 mesh volumes and 1,000 iterations for each case.
