Abstract
The air, fuel vapor and droplets flow through an engine induction system is studied by a one-dimensional two-phase steady flow model that includes evaporation and heat transfer through the manifold wall. The conservation equations and pertinent constitutive relations are solved numerically by the Bulirsch-Stoer integration scheme. A parametric study of exhaust gas recirculation, fuel type and initial droplet size on evaporation is carried out. Heating of the manifold walls is found to be the most effective way to reduce droplet size and to improve evaporation.
