Abstract:

Numerous advanced combustion-diagnostic techniques have been developed evaluated for flame studies. These techniques include a combined coherent anti-Stokes Raman spectroscopy CARSlaser-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 Rayleigh, 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 techniques 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 diagnostics techniques.
