The flame temperature of a laminar premixed flame with continuous convex and concave curvatures was experimentally investigated. The flame temperature and the stretch rate along the flame surface were measured for the flame formed in the lean propane/air mixture (φ = 0.72, Lc = 1.74). As a result, the flame temperature at the convex toward the unburned mixture was lower than the adiabatic flame temperature and that of the concave was higher, because of the flame stretch and the Lewis number effect. However, the measured flame temperature was different from the estimated flame temperature by the theory for the local flame structure proposed by C. J. Sun et al. We guess the reason why such difference was arisen is the existence of the heat transfer along the flame surface, so we suggest that the heat transfer along the flame surface should be considered in the case of the flame with continuous convex and concave curvatures.
