with the resulting size distribution being quite broad
( ¯ d = 22 μm, ¾d = 13 μm). Downstream, a Phase Doppler
Interferometer (PDI) (15) simultaneously measures the
diameter (di), downstream speed (vi), and arrival time
(ti) of any droplets that traverse its view volume (which
has a linear dimension of roughly 150 μm). The PDI system
was built and calibrated by Artium Technologies, Inc.
and is designed for in situ measurement, such that the instrument
does not disturb the flow through the measurement
volume when aligned parallel to the mean flow.详细>
