Optische Partikelgrößenbestimmung im Sub-Mikrometer-Bereich in Flammen
Abstract
An optical system for measuring size and concn. of particles <1 .mu.m in flames is described. The measuring-system is working non-intrusive and has been built up in an exptl. scale. The function of the system is based on a multiple-wavelength-extinction method. In case of sufficient particle-concn. in sooting flames, the system is able to detect particle-sizes in a range of 0.01-0.5.mu.m. Addnl., the plume of an Al-filled composite propellant was investigated.
