  • 利用电荷耦合器件摄像机采用烟黑温度场和浓度场同时重建模型对自由火焰烟黑的三维温度场和浓度场进行了同时重建实验研究,所利用的重建模型是基于区域重建的方法.将重建的烟黑温度场和浓度场与文献结果进行了对比,而且还将重建温度场与热电偶所测量的温度场进行了对比.结果表明,重建的烟黑温度场和浓度场与文献结果趋势相一致,重建温度值与热电偶测量值符合较好.因此,同时重建模型可以较好地重建出火焰烟黑的三维温度场和浓度场.

     

    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.
