| Research Abstract |
For the fundamental combustion research of isomer biofuels, experiments of propanol isomers and propane turbulent premixed flame using OH-PLIF were performed in a high pressure environment. The local flame surface density for each fuel was analyzed from instantaneous turbulent flame images of cross-section. The results of the flame surface density analysis indicated differences of intrinsic flame instability for 1-propanol, 2-propanol and propane. Numerical simulations of intrinsic flame instability using a two-step reaction model as well as 1-D laminar flames using detail chemistry for propanol and propane/air mixtures were carried out to clarify the relationship between chemical reaction and flame instability. It was clarified that turbulent flame structure is highly affected by the diffusive thermal effects of C2 intermediate species, which depends on the isomer fuels and differences in dissociation reaction pathway.
