Vehicle Soiling Simulation
Well-established and efficient CFD methodologies are exploited at ICON. These include Lagrangian-Eulerian two-phase and coupled particle tracking of discrete particles in an airflow continuum, liquid-film formation due to impingement of droplets on the surface, resulting liquid-film transportation, and droplet stripping (re-entrainment) back into the continuum airflow due to edge effects of film instability. A liquid film transportation model accounts for many physical effects including film-continuum shear, pressure-gradient, gravitational and inertial effects.
Validations of these methodologies are performed by ICON together with their application to production vehicles.
