摘要
给出了多层球形墙体的热传递矩阵 ,提出了用频域回归 (FDR)方法计算球形墙体瞬时传热的方法。实例计算表明 :用FDR方法计算球形墙体瞬时传热不仅简单快速 ,而且计算精度高。
Presents the transmission matrix of heat transfer of multilayered spherical walls and introduces the calculation procedure of frequency-domain regression(FDR) method.The results of calculated examples show that FDR method is very simple and fast and has high accuracy in calculating the transient heat transfer of multilayered spherical walls.
