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.
The charge-coupled device camera is used to reconstruct the three-dimensional temperature field and concentration field of free flame smoke black with the simultaneous reconstruction of smoke temperature field and concentration field. The reconstruction model is based on the method of region reconstruction. The temperature field and concentration field of smoke black are compared with the literature results, and the reconstructed temperature field is also compared with the temperature field measured by thermocouple. The results show that the reconstructed smoke temperature and concentration field accord with the literature results , And the reconstructed temperature value is in good agreement with the thermocouple measurement value.Thus, reconstructing the model can reconstruct the three-dimensional temperature field and concentration field of flame smoke black well.
