Methane and hydrogen-enriched (25 vol% 50 H2-enriched CH4) methane/air premixed flames were investigated in a gas turbine model combustor under atmospheric conditions. The flame operability ranges mapped at different Reynold numbers (Re), showing the dependence on Re H2 concentrations. effects of equivalence ratio (Φ), Re, enrichment structure examined employing OH-PLIF measurement. For CH4/air cases, was stabilized with an M shape; while for transitions to П shape above specific Φ. This...
An experimental and numerical study on thermal chemical effects of water vapor addition the laminar burning velocities syngas was conducted using a constant-volume chamber CHEMKIN package. The conditions in present for CO/H2/air/H2O mixtures with hydrogen fraction were from 5% to 50%, initial temperature 373 K, pressures 0.1 0.5 MPa dilution ratios 0% 30%. measured velocity data compared simulations three mechanisms, San Diego mechanism those Davis et al. Li showed reasonable agreement...
Large-eddy simulation with a finite-rate chemistry model is carried out to investigate the formation of soot and nitrogen oxides (NOx) in dual-fuel spray combustion. Liquid n-heptane injected into constant volume chamber, filled premixed methanol–air mixture an equivalence ratio (ϕm) 0.3. Three cases are simulated under initial temperatures 900, 950 1000 K. single-fuel cases, same configurations, but pure air being used as ambient gas composition also baselines for comparison purposes. The...
Experimental and numerical studies were performed to understand the stabilization of lean premixed natural gas/air flames in a gas turbine model combustor which was equipped with swirl burner, known as CECOST designed replicate flow flame structures an industrial engine. The operability range, stabilization, flashback investigated employing simultaneous OH– CH2O-PLIF, high-speed chemiluminescence imaging. Large eddy simulation (LES) carried out for analysis vortex breakdown under...
Clean technology has become a key feature due to increasing environmental concerns. Swirling flows, being directly associated with combustion performance and hence minimized pollutant formation, are encountered in most propulsion power-generation devices. In this study, the development process of conceptual swirl burner developed at Swedish National Centre for Combustion Technology (CeCOST), is presented. Utilizing extensive computational fluid dynamics (CFD) analysis, both lead time cost...
In a piloted jet flame, the pilot flame has an effect of stabilizing main flame. Detailed mechanisms flame/main interaction are however not well studied. It is expected that affects through following mechanisms: (a) provides heat and radicals to reaction zone (b) prevents cold ambient air from being entrained into (c) modifies stretch rate this paper, detailed numerical simulations laminar methane/air flames carried out elucidate on structure burning velocity One-dimensional (1D) freely...
