The Aerodynamics Simulation of Air Ventilation Performance and the Process Development of Air Ventilation Design Tool

This study validated the process of air ventilation design and the increase of air ventilation performance using CFD(Computational Fluid Dynamics). The application to computing external flow include passenger compartments are designed by one model using new method. 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. Achievement of these design guides and new development process will be satisfied with predicting the ventilation performance in a short term and cutting down expenditure.
