The surface temperature of a burner nozzle using three different pilot hardware configurations was measured lifetime phosphor thermometry with the ZnS:Ag in gas turbine model combustor designed to mimic Siemens DLE (Dry Low Emission) burner. included non-premixed injection setup and two partially premixed injections where one had relatively higher degree premixing. For each configuration, operated either methane or hydrogen-enriched (H2/CH4: 50/50 volume %). local heating from flames much...
Abstract In this study, the laser induced fluorescence lifetime of Ni atoms in ambient air with presence a plasma discharge was measured for first time. Free were generated by spark plug driven an inductive coil. Decay curves LIF excited 336.94 nm, 90 ps pulse captured PMT. An average about 1.1 ns observed signal within 7.4 nm detection window centered at 345 nm. Further analysis also revealed that transition showed statistically insignificant change throughout duration discharge. The peak...
Abstract In this study, the laser induced fluorescence lifetime of Ni atoms in ambient air with presence a plasma discharge was measured for first time. Free were generated at pressure 1 bar by spark plug discharges driven an inductive coil. The excited 336.957 nm absorption line 336.96 nm, 90 ps pulse and resulting temporally resolved decaying signals captured PMT. An effective about 1.1 ns observed signal within 7.4 detection window centered 345 nm. Further analysis also revealed that...
Correction to Effective lifetime of Ni laser induced
The reduction of greenhouse gas emissions and the effort carbon neutrality require improvement spark-ignition engines in terms efficiency capability to operate on renewable fuels. electrode wear spark plugs, used for ignition novel fuels lean mixtures, emerges as a significant challenge this transition. Understanding physical mechanism influence operation parameters process is thus important. Compared conventional methodology performing long-term tests, laser-based optical diagnostics...
