The catalytic and gas-phase combustion of fuel-lean H2/CO/O2/N2 mixtures over palladium was investigated experimentally and numerically at a global equivalence ratio φ = 0.285, H2:CO volumetric ratios 1-4, pressures 1-8 bar and catalyst surface …
The heterogeneous and homogeneous combustion of C3H8/O2/N2 mixtures over Rh was investigated at pressures 1-6 bar, catalyst surface temperatures 680-1100 K and C3H8-to-O2 equivalence ratios 0.25-0.52. Non-intrusive laser-based measurements were …
Ammonia combustion, owing to its zero greenhouse gas CO2 emission, is attracting attention for energy utilization. However, the thermal radiation of NH3 has not been reported and involved in the numerical simulations of ammonia flames, which may …
The involvement of hydrocarbons such as C2H4 and its combustion intermediate species C2H2 in thermal radi- ation has not been accounted in the numerical simulations of literature studies, which may in turn cause errors in estimating the soot …
The effects of adding acetylene to the fuel stream on soot formation and flame properties were investigated numerically in a laminar axisymmetric coflow ethylene/air diffusion flame using the open-source flame code Co-Flame in conjunction with an …
Gas radiation is a major way of heat transfer in flames. It affects temperature distributions and hence causes energy transfer in the combustion gaseous as well as subsequent chemical reactions. Accurate and efficient modeling of radiative heat …
Coupled reduced mechanisms were developed for the hetero-/homogeneous combustion of fuel-lean and fuel-rich H2/CO/O2/N2 mixtures in a Pt-coated planar channel, using a method based on the Directed Relation Graph (DRG) and for a wide range of …
Kinetic interactions between H2 and CO over PdO, a widely used catalyst in combustion systems, were studied experimentally and numerically. Global reaction parameters of H2 and CO oxidation over PdO were extracted from wire microcalorimetry …
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 …
