Content
The thermal fluid field in a headlamp based on the real 3D-CAD model is analyzed by a mesh free method. The conducted method is a new CFD (Computational Fluid Dynamics) solver based on the couples of the points whose density is controlled scattered in the analysis space including the boundaries, which leads to much reduce the hand-working time in the deformation of the 3D-CAD model for the mesh generation. This paper focuses on the steady state airflow field in a headlamp under the conditions of natural ventilation including the effect of the buoyancy and the heat generation of the lamp surface for the demonstration of the conducted method without not only the deformation of the real 3D-CAD model but mesh generation. The differences of the pressure outlet conditions and heat generation of the headlamp on the amount of the ventilation are also experimented. As a result, it is found that the conducted method is recognized as a powerful tool which can analyze the thermal fluid field in the headlamp based on the real 3D-CAD model directly with simple operation.
