Impact of non- ideal fluid modeling on droplet evaporation for aerospace applications

Liquid droplet vaporization is a rate-limiting process in many chemical aerospace propulsion systems. In recent years, due to stringent emission standards, the development of low-emission jet-aviation combustors has focused on increasingly higher overall pressure ratios (OPRs), intending to reduce greenhouse gas and unburned hydrocarbon emissions, implying non-ideal classes of thermodynamic trajectories encountered during the vaporization, for which accurate modeling is crucial. A lumped discrete-components approach is presented, including real-fluid models accounting for high-pressure effects and the vapor-liquid-equilibrium method. This provides a free-standing framework that aims to evaluate the impact of non-ideal fluid modeling on the droplet vaporization phenomena.
