Combustion Diagnostic Development and Application. Volume 1
Abstract
Numerous advanced combustion-diagnostic techniques have been developed and evaluated for flame studies. These techniques include a combined coherent anti-Stokes Raman spectroscopy (CARS)/laser-Doppler velocimetry (LDV) system for simultaneous temperature and velocity measurements; thin-filament- pyrometry (TFP) for high-speed, multi-dimensional thermometry; flame- visualization techniques REACTIVE Mie scattering (RMS). two dimensional Ralyleigh, and planar laser-induced fluorescence (PLIF) of the OH Radical for obtaining two-dimensional flame-structure information; two-color particle- imaging velocimetry (PIV) for two-dimensional velocity measurements in low- and high-speed flowfields; hardened CARS system for thermometry in large-scale combustion systems; and a combined CARS/phase Doppler particle analyzer (PDPA) system for temperature, velocity, and particle-size measurements in spray- combustion systems. In addition, the LDV technique was utilized extensively for pointwise velocity measurements. These techniques were developed, evaluated, and applied to the study of turbulent combustion flames. Experimental results obtained with the advanced diagnostic instrumentation were used in the evaluation of several numerical flame models. Both small (Bunsen and jet diffusion flames) and large (6- and 10-in.-diam. combustors) systems were studied utilizing the advanced diagnostic techniques.
