✦ Synopsis

A new technique has been developed that produces instantaneous or time-averaged two-dimensional images of Sauter Mean Diameter from a spray. Laser Sheet Dropsizing (LSD) combines elastic and inelastic light scattered from a laser sheet. Compared with Phase Doppler Anemometry (PDA), the new technique oers advantages in increased spatial and temporal resolution and more rapid spray characterisation. Moreover, the technique can also be applied to dense sprays. Successful implementation requires careful calibration, particularly of the eect of dye concentration on the dropsize dependence of the inelastic scattered light.
