The process that BTECHC wants to improve is the thermal simulation of the lighting systems design for cars. The development of head and rear lamps is totally conditioned by the outer style surfaces. Most of the times, the lamp design becomes one of the main items in order to obtain an attractive and differentiated style. Often this forces lamp designers to work with reduced spaces. Heat dissipation is very difficult in these conditions and the plastic material may degrade, losing its optical and esthetic properties, and even causing failure in bulb and led carriers.The main goal for this kind of simulations is to obtain the temperature gradient all over the lamp to verify the thermal material resistance and the mechanical resistance due to the thermal stresses.The current procedure for this kind of simulation takes from 3 to 4 weeks, and consists of several steps: geometry simplification, mesh model, CFD model and solver, CFD post processing and structural analysis.
The target is to simplify the methodology to simulate, using free software, namely OpenFOAM and Code-Aster, heat extraction in thermal sourcesthrough numerical methods, and specifically to analyze automobile lights designs. To this aim CloudFlow tools(WFM, WFE…) will be used to simplifythe whole process by automating the workflow of the HPC work.
