Abstract

The thermal comfort of passengers is a priority concern in India’s metro rail system as it affects both psychological and physiological character while traveling in the train compartment. The principal factors affecting human thermal comfort are the air temperature, its relative humidity, the mean radiant temperature and the relative air velocity which varies due to various human load inside cabin. Hence in this work, the CFD tool ANSYS FLUENT 18 software package was used for numerical analysis of cooling load, air flow and heat transfer in our virtual 2-D and 3-D model of the metro train’s passenger cabin/compartment so as to analyze the level of comfort that passengers experience in different climate zone cities mainly Chennai, Delhi and Kolkata. This work also tries to validate how the required temperature and air distribution for passengers is maintained for different scenarios like normal time and peak time inside a metro rail coach for the above-mentioned cities. The result, analyzed and discussed in terms of temperature and velocity fields for different scenarios/cases, shows an adequate behavior from the passengers’ comfort point of view.
