Data consistency of the burning velocity measurements using the heat flux method : Hydrogen flames

摘要: Abstract Consistent datasets of experiments are highly important both for validation and optimization kinetic mechanisms. An analysis the data consistency all available burning velocity measurements hydrogen flames using heat flux method at atmospheric pressure is performed in present work. A comparison many several laboratories with different types dilution by various inerts was guided modeling two Konnov (2015) ELTE (Varga et al., 2016) models demonstrated a uniform trend conditions tested: second mechanism predicts lower velocities which better agreement from groups. Some experimental datasets, however, significantly disagree one or models; these were revisited experimentally The laminar H2 + O2 + N2 mixtures 7.7% O2 O2 + N2 oxidizer 85:15 (H2 + N2) 25:75 fuel 12.5:87.5 (O2 + He) have been measured. It concluded that results Hermanns et al. (2007) somewhat higher than those other studies similar possible reason this disagreement suggested. Analysis Goswami on high-pressure installation suggests an equipment malfunction led to erroneous values equivalence ratio syngas flames. developed approach shows very good performance predicting measured method.
