Fundamentals of fuel film formation and motion in SI engine induction systems

In spark ignition engines the intake fuel flow exists in several streams, these being vapour, liquid droplets and liquid wall film. This research is aimed at examining fuel film behaviour in general, the particular emphasis being on the application of fundamental experiments in an especially designed rig and numerical simulation to obtain a better understanding of film formation. A number of specific configurations have been examined by both techniques. The numerical results correspond reasonably well with the assessment from the rig.
