| Abstract: | Aiming at a certain EMU （electric multiple units） first carriage the interior flow field calculation model of cab and passenger compartment was established and numerical calculation on interior flow field of cab and passenger compartment and its air conditioning was performed by using computational fluid dynamics numerical simulation method,κ-ε standard turbulence model and the SIMPLE algorithm.The detailed information of the flow parameters were obtained,and the temperature field and velocity field of cab and passenger compartment of first carriage were assessed with UIC 553-1-2005 （Heating,ventilation and air-conditioning in coaches-standard tests）.It proves that the air-conditioning ventilation system meets human comfort requirements,and the design is reasonable. |
