文摘
- •
A new skeletal diesel surrogate model is developed for combustion and soot modelling.
- •
When liftoff lengths drop, local equivalence ratio of the rich premixed core rises.
- •
In-cylinder phenomena in a two-stroke, uniflow-scavenged marine engine are studied.
- •
The averaged NO concentration is 7.7% lower as soot radiation is considered.
- •
Total heat transfer to walls is 30% higher as soot radiative heat loss is considered.
