- 摘要：
- The laminar burning velocity of iso-butanol-air mixtures was measured under different initial pressures, initial temperatures and equivalence ratios using high-speed schlieren photography and outwardly propagation flame in a constant volume combustion bomb. Based on the analysis of stretched flame propagation speed and stretch rate, the laminar burning velocities and Markstein lengths of iso-butanol-air flames are obtained. In accordance, with photos of flame, an analysis of flame stability and the influencing factors are carried out. The results show that the laminar burning velocity is decreased with the increase of initial pressure and is increased with the increase of initial temperature. The maximum value of laminar burning velocity is presented at the equivalence ratio of 1.2. The Markstein length is decreased with the increase of equivalence ratio. For specified equivalence ratio, the Markstein length is decreased with the increase of initial temperature and initial pressure. Thus, the flame instability is in-creased with the increase of equivalence ratio, initial temperature and initial pressure
