Supercritical atomisation visualisation for pilot injection events

High energy X-rays at ANL will characterise initially the liquid/vapour distribution inside the nozzle’s sac volume for different fuels/additives both for clean and aged injectors with deposits. High speed imaging in CVC will then characterise the liquid atomisation near the nozzle exit for pilot injection events, aiming to link the amorphous ligaments formed at the nozzle exit with the nozzle geometry/flow.
