摘要
本文用反应系数法取代目前在特朗贝式集热墙不稳定传热计算中传统的差分解法,不仅可以节省计算机的内存和机时,方便地求得集热墙体的内外表面温度,而且更适用于计算由多种材料层构成的复合墙体,输入格式简便。另外,本文还对集热墙夹层空气流道的流量计算方法作了改进,给出了可用直接法求解的集热墙热平衡联立方程组。
In this paper, response factors method is used instead of the traditional finite difference method in numerical calculation of unsteaty state heat transfer for the collector-storage wall. Compared with the traditional method(1,2,3), this one can economize on computer memory and calculation time, and it is more easy to calculate the multilayer wall by simply input format. In addition, the calculating method of the air mass flow rato in the collector-storage wall gap is also improved, and the equation set which can be solved by direct method is presented to calculate the collector-storage wall heat balances.
