RISSpatial Temperature and Water Molar Concentration Measurements Using Thermal and Electrostrictive Laser-Induced Grating Spectroscopy During Operation of a Swirl Burner at Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser-Induced Grating Spectroscopy (LIGS) was applied in a high-pressure combustion facility. Instantaneous (sub-μs), spatially resolved (within 5 mm) measurements of temperature and molar fractions of water were obtained ...
Spatial Temperature Measurements in a Swirl-Stabilized Hydrogen–Air Diffusion Flame at Elevated Pressure Using Laser-Induced Grating Spectroscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser-induced grating spectroscopy (LIGS) is applied, for the first time, to a swirling nonpremixed hydrogen–air flame in a high-pressure combustion facility. A portable LIGS unit is used to probe 35 different axial and ...
Characterization of Additive Layer Manufacturing Swirl Burner Surface Roughness and Its Effects on Flame Stability Using High-Speed Diagnostics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, two Inconel 625 swirl nozzle inserts with identical bulk geometry were constructed via additive layer manufacturing (ALM) for use in a generic gas turbine swirl burner. Further postprocessing by grit blasting ...
