چکیده

The present paper presents applications and feasibility studies of a number of laserspectroscopic techniques in a lean premixed prevaporised (LPP) combustor. Four different laser diagnostic techniques were investigated. The two more mature techniques, Planar Mie Scattering/Laser Induced Fluorescence and Planar Laser Induced Fluorescence of OH were used for fueland OHvisualisation, respectively. In addition, the applicability of some novel techniques in harsh industrial environments were investigated, two-line atomic fluorescence (TLAF) to obtain 2-dimensional temperature distributions, and two-photon LIF for the detection of CO. In order to investigate the degree of turbulence an ultrafast framing camera was employed to record spontaneous emission.

Multi-Intensity-Layer PIV application to a Gas Turbine Combustor

The new technique ‘Multi-Intensity-Layer PIV’ was applied to a gas turbine combustor to detect the instantaneous droplet distribution and its behavior. Mie scattering theory is applied to the conventional Particle Image Velocimetry and the technique enables us to detect the instantaneous planar droplet velocity and size information. This M-PIV technique was evaluated with a generally used indus...

Experimental study of soot aerosol formation in swirl-stabilized flames of alternative aviation fuels on a path to sustainable aviation

Particulate matter (soot aerosol or carbon black) emissions from combustion systems have adverse effects on human health and the environment. Soot is a major contributor to the total radiation heat loss in propulsion systems. Soot aerosols in the atmosphere have significant positive radiative forcing that contributes to global warming because of strong absorption of sunlight by soot. As compare...
