An experimental multiparameter investigation on the thermochemical structures of benchmark ethylene and propane counterflow diffusion flames and implications to their numerical modeling

Effects of Ammonia Addition on the Sooting Characteristics of Ethylene Counterflow Diffusion Flames with Oscillating Strain Rates

“…Flames. The present measurements were conducted based on a newly designed unsteady counterflow burner 61 (see Figure 1), which is an upgrade from a previous steady counterflow burner 62 by introducing additional loudspeakers to generate controllable acoustic forcing. For that reason, we provide only a brief description here.…”

Mid‐infrared multiline absorption tomography for in situ analysis of thermochemical structure in natural gas‐fired cooker flame

“…Regarding CO 2 measurements, a sampling probe with a flue gas analyzer, gas chromatography, or Fourier transform infrared spectrometer is typically used for ex situ measurement. [9][10][11] As the sampling probe would perturb the local combustion field and the gas species composition may change due to sample losses and chemical reactions, the measurement fidelity may be undermined.…”

“…Note that, such corrections are nontrivial because the desired local gas thermal conductivity and Nusselt number 8 are hard to be determined for the unknown combustion field. Regarding CO 2 measurements, a sampling probe with a flue gas analyzer, gas chromatography, or Fourier transform infrared spectrometer is typically used for ex situ measurement 9–11 . As the sampling probe would perturb the local combustion field and the gas species composition may change due to sample losses and chemical reactions, the measurement fidelity may be undermined.…”
