Effects of radiation reabsorption on the burning flux of freely propagating laminar premixed flames at atmospheric and elevated pressures were numerically investigated for CH4/O2/N2/CO2 mixtures. Models with SNBCK 9 bands and 7 bands based on the …
Biomass combustion for heat and power generation is one of the best ways for substituting fossil fuels. It is necessary to develop in situ temperature and emissivity measurement technology for biomass volatile flame. In this study, combustion …
The heterogeneous and homogeneous combustion of fuel-lean CH4/O2/N2 mixtures over PdO was investigated experimentally and numerically at equivalence ratios φ = 0.27–0.44, pressures 1–12 bar and surface temperatures 710–1075 K. In situ Raman …
The chemical interactions between CO and H2 over rhodium were investigated for H2/CO/O2/N2 mixtures with H2:CO volumetric ratios 1:5–3:1, overall fuel-lean equivalence ratios φ = 0.13 and 0.23, a pressure of 5 bar, and surface temperatures 510-610 K. …
To improve the efficiency of full-spectrum correlated-k-distribution (FSCK), a new method FSCK-RSM has been proposed based on response surface methodology (RSM) in this paper. The k-distributions of FSCK was used to fit the response surface model …
The catalytic combustion of fuel-lean H2/CO/air and H2/CH4/air mixtures (equivalence ratios φ = 0.3–0.5) was investigated experimentally and numerically in a 30×30×4 mm^3 microreactor made of SiC and equipped with six 1.5-mm internal diameter …
The heterogeneous and homogeneous combustion of fuel-rich CH4/O2/N2/CO2 mixtures (equivalence ratios φ = 1.8–3.5) was investigated experimentally and numerically at 5 bar. Experiments were carried out in an optically accessible channel-flow reactor, …
The hetero-/homogeneous combustion of CH4/O2/N2 mixtures over rhodium was investigated experimentally and numerically at fuel-lean equivalence ratios φ = 0.30–0.40, pressures 2–12 bar, and catalyst temperatures 700–1250 K. Experiments were performed …
The hetero-/homogeneous combustion of fuel-rich H2/O2/N2 mixtures (equivalence ratios φ = 2.5-6.5) was investigated experimentally and numerically in a platinum-coated channel at pressures p = 1-14 bar. One-dimensional Raman measurements of major …
The catalytic and gas-phase combustion of fuel-lean H2−O2−N2 premixtures was investigated in a channel coated with platinum at pressures 1.0−3.5 bar, a range encompassing microreactors in portable power generation systems and passive hydrogen …
