Optische Messungen der Dichte der von Azetylen Gebildeten Rußteilchen

The density of acetylene-soot was obtained by making measurements using light extinction at 3.392 µm with an infrared He-Ne laser. Acetylene-soot was produced behind a reflected shock wave using a “tailored”-interface shock tube. The obtained value was 0.9± 0.2 g/cm 3 at temperatures from 1500 to 20...

Summary:The density of acetylene-soot was obtained by making measurements using light extinction at 3.392 µm with an infrared He-Ne laser. Acetylene-soot was produced behind a reflected shock wave using a “tailored”-interface shock tube. The obtained value was 0.9± 0.2 g/cm 3 at temperatures from 1500 to 2000 K. This value agreed with the value of benzene-soot which was measured using the same optical system with a normal shock tube. The wavelength dependence of the emission intensities due to soot particles, produced behind the reflected wave, agreed well in the visible and infrared regions with that of grey-body radiation.
