In order to improve thermal endurance, mechanical durability and ventilation performance in an automotive headlamp, it is important to understand heat transfer and flow. In the present study, a newly-developed method called surface heat transfer (SHT) method, a unique technique for making an accurate estimate of temperature and velocity in the automotive headlamp without involving the use of fluid mechanics and structural mechanics, was investigated for practical use. An evaluation of SHT method was performed, and CFD results were compared with the experimental results.
