一维平行平板系统介质辐射参数和高浓度区域高度的同时重建

     

摘要

不同浓度区域介质辐射参数对炉膛辐射传热计算有着十分重要的作用.基于牛顿法和最小二乘法对一维平行平板系统辐射参数和高浓度区域高度的同时重建进行模拟研究.结果表明,在有限的迭代次数内,重建参数能收敛在真值附近,并且介质辐射参数在真值附近振荡,而其振荡范围基本不变;随着测量误差的增大,重建误差也逐渐增大.%Radiation parameters to medium in different concentration areas are very important for the calculation of radiation transfer in a furnace. Based on Newton method and least square method, the simulative research on simultaneous reconstruction of radiation parameters to medium and the height of high concentration areas in a one-dimensional parallel plate system was carried out. The simulating results indicate that reconstruction parameters can be convergent to true values and concussive while the fluctuation range keeps fixed on the whole. With the increase of measurement errors, reconstruction errors gradually increase.
