Abstract:The physical model of 25K hard-seat air-condition train was designed.The thermal environment for train with cold air distrbution system was simulated numerically by K-e turbulent model and CFD software.The result indicates that the thermal environment for train with cold air distribution system can meet the demand of comfortable degree of occupants,the system can be applied and spreaded for the train air-condition.The result is significant for the spreading of cold air distribution system.
Keywords:air-condition train  cold air distribution system  thermal environment  numerical simulation
