Abstract - The shape and configuration of the air ventilation system determine the ventilation performance. Therefore, the air ventilation system configuration in the early stages need the aerodynamics simulation results of the cowl top, intake duct, blower, HVAC, passenger room and exit. The usage of CFD tool is needed for the ventilation system design in vehicle. This study validated the process of air ventilation design and the increase of air ventilation performance using CFD(Computational Fluid Dynamics) and test in development vehicles. The external, ventilation system and passenger compartments parts are made by one CFD mesh model and the CFD results are compared by a field test easily. This process is satisfied with predicting the ventilation performance in a short term and cutting down expenditure.
