摘要：

Three-dimensional (3D) flame soot temperature and volume fraction distributions are simultaneously reconstructed experimentally by the simultaneous reconstruction model through using charge-coupled device cameras. The reconstruction model is based on the area reconstruction. The reconstructed 3D soot temperatures and volume fraction distributions are compared with those reported in the literature. The reconstructed temperatures are also compared with those measured by thermocouples. It is shown that the reconstructed temperature distribution and the volume fraction distribution are consistent with the reported results. The reconstructed temperatures in good agreemant with the measured temperatures by thermocouples. So the simultaneous reconstruction model can obtain the soot temperature and volume fraction distributions successfully.
