Effects of radiation absorption on spherical flame propagation and radiation-induced uncertainty in laminar flame speed measurement

Outwardly propagating spherical flames are popularly used to measure the laminar flame speed, especially for high pressure conditions. Since radiation always exists in spherical flame experiments, the accuracy of laminar flame speed measurement is inherently affected by radiation. In this study, the radiation-induced uncertainty in laminar flame speed measurement was investigated numerically. We focused on CO2 diluted mixtures in which the...
