direction: right to left
Nozzle dimensions: w=200µm, l=1mm
Pressure: 32 bar
Flash duration: 20ns
highlighted parts are the nozzle edges and the edges of the cavitationfield.
Apart from these areas, the double-illuminated particles can
be clearly located in two positions of their flow.
(red circles indicate these two positions, violet circles indicate
dirtparticles, which return in every image).
In the shown images, velocities of 67 to 80m/s were measured.
images were taken with the Nano Twin Flash system.
