Throughout this study a lab scale atomizer with a maximum charge weight of approximately 10 kg has been used. A Photron FASTCAM-X high-speed imaging camera was used to study the melt flow disintegration. The camera has a maximum frame rate of 109500 frames/s and shutter times down to 1.5 μs. This makes it possible to capture fast processes during atomization. The movies show a turbulent flow behavior with short primary break-up lengths (~1-2 cm). General particle speeds are in the range of 100-200 m/s where the smallest particles are even faster. The use of high-speed imaging cameras provides the means to study e.g. melt breakup, disintegration lengths, effect of different nozzle designs, and particle speeds, parameters that are of interest during process development and optimization.
