Summary:

The vehicle windshield defogging performance has directinfluence under driver safety. In extreme situations, when thevehicle is not equipped with air conditioner and loaded withmaximum occupancy, the defroster system must correctly direct theflow in order to defog pre-defined regions on the windshield. Thisprocess can't take too long and must guarantee a minimumfog-free area to increase driver's visibility.The main objective of this paper is to demonstrate the defoggingsimulation methodology developed by FIAT Brazil and MulticorposEngineering. It uses CFD simulations with StarCCM+ software.Experimental data obtained from climatic chamber is used to comparethe numerical data and validate the methodology.The simulations were able to conclude that defogging performanceis correlated to flow homogeneity and its mean velocity on theinternal windshield area. CFD simulations were used to indicate finangles that can enhance the fog layer removal
