Kurzbeschreibung (Abstract)
In this work the differences between ideal and non-ideal vapor-liquid-equilibrium (VLE) and the effect on vapo- rization for multicomponent hydrocarbon fuels, which are representative for engines or gasifiers, are investigated. Based on these deviations, a parametric study of non-ideal VLE-behavior for a pressure range of 0 . 5 - 20 . 0 bar and a temperature range till 600 ◦ C, which are typical vaporization conditions in technical systems, is performed. The VLE results are then applied for a 0D single droplet vaporization model, which can be considered as a base model for most CFD applications. The droplet life time and the vaporization rates of the single components are compared between ideal and non-ideal behavior varying the pressure, the temperature and the particle Reynolds number. The observed differences suggest that non-ideal VLE have a significant impact on the droplet vaporization characteris- tics for complex hydrocarbon mixtures.
