报告摘要:

The laminar burning velocity (LBV) is one of the most important parameters of a combustible mixture. Various experimental approaches have been developed to measure LBV, among which the outwardly propagating spherical flame (OPF) method is popularly used, especially at high pressures. There are great challenges in accurate measurement of LBV. In this talk, the discrepancies in LBV measured for CH4/air at normal temperature and pressure using the OPF method will be introduced first. Then, the recent advances in accurate measurement of LBV will be introduced. Specifically, the possible sources of uncertainty in LBV measurement are investigated and their contributions to large discrepancies in laminar flame speed measurement are assessed. The recommendations on LBV measurement using the propagating spherical flames will also be provided.
