In order to predict water condensation in an automotive headlamp at an early stage of the development process, CFD analysis of the flow in the headlamp was attempted. First, CFD analysis was conducted on the headlamp unit removed from a vehicle. The result was similar to the experimtal result, thus the validity of this was confirmed. Furthermore, water condensation in the headlamp on the vehicle was studied based on the CFD analysis and the experiment. The results show that the water condensation in the headlamp is not only influenced by the velocity and temperature distribution in and around the headlamp, but also by the absolute humidity near the headlamp vents.
