二维真空系中壁面辐射热负荷反问题

An Inverse Problem of Wall surface Radiation heat Load in a Two dimensional Vacuum System

在MonteCarlo法的基础上用特异值分解法 (SVD)与共轭梯度法 (CGM )分别求解了壁面辐射热负荷反问题。计算结果表明 ,考虑测量值误差时 。

Based on a Monte Carlo method and through the use respectively of a Singular Value Decomposition method (SVDM) and a Conjugate Gradient Method (CGM) solved in this paper is the inverse problem of a wall surface radiation heat load. Calculation results show that when the error of measured values is taken into account the stability and precision of the solution by the CGM are by far higher that those of the solution by the SVDM method.
