Abstract: The research described here addresses the problem of a paucity of
high quality data on the full field structure of high pressure liquid fuel
sprays for gasoline direct injection, GDI, engines. The paper describes the
application of phase Doppler anemometry, PDA, and single-shot laser sheet Mie
imaging to the study of GDI sprays and discusses the methodologies adopted for
the experimental systems and the optimisation of the techniques. Experimental
data is presented which defines the spray structure in terms of PDA vector and
scalar fields and single-shot CCD digital images. The work demonstrates the
essential complementary nature of the single point and planar optical
diagnostics for spray studies.
