A new CFD method using a meshfree collocation approach to resolve water evaporation is developed since it is essential to estimate the water dry-out-time for corrosion protection schemes on vehicle components. Thereby, volume-volume-coupling, and diffusion-based water transfer into vapor is used. Adaptive refinement enabling the automation of the whole process is also developed. The new method is validated with a simple geometry and an actual vehicle geometry. The total-dry-out times of accumulated water source at the corner of the sunroof are measured. To extend the time scale of simulation to real, the evaporation rate is artificially accelerated. The validations are promising could be further extended.     «
