The behaviour of a liquid kerosene spray injected
into a cross-flow of high temperature vitiated air is in-
vestigated. This fundamental flow configuration has
wider implications for the design of future aeronauti-
cal fuel injectors, particularly with respect to MILD
combustion concepts. Large eddy simulation is ap-
plied to numerically study the global flame character-
istics, with the main objectives of giving further in-
sight into the reacting behaviour of sprays in cross-
flow and comparing two different approaches to model
turbulence-chemistry interaction: the conditional mo-
ment closure model and the Eulerian stochastic fields
method. Results show that the two approaches give
similar predictions of the location of the peak mean
temperature. Some differences appear in the vicinity
of the spray injection location, possibly highlighting
the important role of the modelling of the interaction
between evaporation and sub-grid mixing. Analysis
of the flame and spray behaviour at different pressures
also demonstrates the strong coupling between the re-
acting field and evaporation characteristics, which are
highly affected by the penetration of the spray into a
flow field characterised by relatively large gradients of
temperature. Results obtained in this work provide a
benchmark for the application of sprays in hot cross-
flow for the development of novel combustion tech-
nologies.
