説明
This study has examined the influence of the addition of hydrogen to propane mixtures on its local burning velocity. Hydrogen added propane mixtures having nearly the same laminar burning velocity with different rates of addition of hydrogen δ_H and equivalence ratios Φ(0.8〜1.4) were prepared. A two-dimensional sequential laser tomography technique was used to obtain the temporal statistical relationship between the flame shape and the flame displacement. The local flame displacement velocity S_F and curvature of turbulent flames were quantitatively measured as the key parameters on turbulent combustion. The Markstein number Ma was also obtained from outwardly propagating spherical laminar flames, in order to examine the effect of positive stretch on burning velocity. It became clear that the trends of the mean values of measured S_F with respect to δ_H and Φ gave good agreement with the turbulent burning velocity. The trends of Ma with respect to δ_H, Φ and fuel types could also explain qualitatively the local burning velocity and turbulent burning velocity.
