Wall Interactions

Spray-wall interactions directly affect fuel-air mixture preparation and emissions formation. They are therefore among the most critical physical processes in engines today. This special issue of International Journal of Engine Research presents 11 papers that investigate spray-wall interactions and their effects at both fundamental and practical levels. This brief article offers background and context for the special issue and summarizes each research paper in the collection.

Crucial Parameter

In turbulent non-premixed combustion applications, such as diesel and direct injection engines, the mixedness of the injected fuel with oxygen and the working fluid inside the combustion chamber is a crucial parameter since it can significantly affect the ignition behavior. In this study, a comprehensive method for investigating mixedness, defined by spatial variation and scalar dissipation, is implemented to assess the turbulent injection of hydrogen into mixture of oxygen with nitrogen, argon, and xenon. Evaluating both criteria reflects the mixture homogeneity as well as local gradients, which aids in discriminating scalar distributions with identical homogeneity and different patterns. The results indicate that replacing nitrogen with argon as the working fluid can provide more suitable ignition conditions for the hydrogen jet.
