文摘The laminar flame speed is one of the most fundamental properties of a fuel/air mixture.It determines the fuel burning rate in combustion engines and is an important target used to validate chemical models.Due to its importance,accurate measurement of the laminar flame speed receives great attention and different experimental methods have been developed.This review first introduces the laminar flame speed as well as its significance and dependence on different factors.Then,different experimental methods for the laminar flame speed measurement are described.Since the outwardly propagating spherical flame method is currently the most popular method for laminar flame speed measurement,its challenges and recent advances are reviewed.Both the constant pressure method and constant volume method using propagating spherical flames are discussed.
