The in-flame soot behavior during the sampling process was visualized via a high-speed visible laser shadowgraphy
. A common-rail fuel injector with a single-hole nozzle was mounted on the head center and the single-shot fuel spray is injected in a horizontal direction in the combustion vessel.
or ombromanie is the art of performing a story or show using images made by hand shadows.
In order to measure the particles size in the test cell and because existing instrumentation could not be used due to size constraints and limited optical access, DGA Aero-engine Testing chose a non-intrusive technique based on shadowgraphy
. The measuring device combine a high-resolution video camera and a 20 ns duration flash: the use of a ultra-short light source is essential for shooting sharp pictures of high speed moving particles.
It covers studying pulse processes, photographic methods of experimental research and high-speed photography, Fourier optics and Fourier spectroscopy, methods of spectroscopy, interferometry and shadowgraphy
methods, holographic methods, electromagnetic probing, measurements in the x-ray region of the spectrum, corpuscular investigation methods, and methods of experimental data processing.
Phase Doppler (laser diffraction technique for the analysis of atomization of multi-ingredient gasoline) also gives good results [23, 24], just like the optical shadowgraphy
that characterizes the injection [25, 15].
