Fluctuations in the fuel flow rate may occur practical combustion systems and result flame destabilization. This is particularly problematic lean ultralean modes of burner operation. In this study, response a ceramic porous to fluctuations different blends methane hydrogen investigated experimentally. Prior injection into burner, blend premixed with air at equivalence ratios below 0.275. The st...

Transport phenomena in porous media are pertinent to thermal and thermochemical processes for power and fuel generation using concentrated solar energy. The porous media serve as insulator, radiant absorbers, heat exchangers, catalyst carriers, reactants, and/or reaction sites. Volume-averaging models for porous media, commonly applied for process simulations and optimization, rely heavily on t...

The manuscript investigated experimentally the influence of two parallel walls on flame geometric parameters and radiative heat flux distributions along wall from fires rectangular burners. Four sets burners with equal area different aspect ratios were used. burner ratios, separation distance between fire release rates systematically varied in tests. Measurements conducted for height evolution ...
