AB  - The behaviour of a liquid kerosene spray injectedinto a cross-flow of high temperature vitiated air is in-vestigated. This fundamental flow configuration haswider implications for the design of future aeronauti-cal fuel injectors, particularly with respect to MILDcombustion 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 modelturbulence-chemistry interaction: the conditional mo-ment closure model and the Eulerian stochastic fieldsmethod. Results show that the two approaches givesimilar predictions of the location of the peak meantemperature. Some differences appear in the vicinityof the spray injection location, possibly highlightingthe important role of the modelling of the interactionbetween evaporation and sub-grid mixing. Analysisof the flame and spray behaviour at different pressuresalso demonstrates the strong coupling between the re-acting field and evaporation characteristics, which arehighly affected by the penetration of the spray into aflow field characterised by relatively large gradients oftemperature. Results obtained in this work provide abenchmark for the application of sprays in hot cross-flow for the development of novel combustion tech-nologies.
