摘要
针对直接空冷系统设计和变工况计算中存在迭代现象,特用C++语言编写了一套直接空冷系统的可视化计算程序,并用算例证明程序的可靠性。用变工况计算程序对已设计好的直接空冷系统进行了计算,得到其变工况热力性能。
Since there exit iterative calculations in the design and study of alternated working condition of DACC, Visual programs about these are introduced in this paper. The programs include there parts, the first is geometric parameters of DACC, then the second is designing calculation, and the third is its alternated working condition calculation. The validity of these programs is verified by use of examples, and the alternated working condition thermal characteristics are provided by using the third program.
