| 摘 要： | 用数值方法求解绕过两圆柱的对流传热问题。贝克列数在０－５０的范围内，了四种不同间距时的传热情况。从中发现两圆柱的传热特性相互有影响，这种影响随意距变化很敏感，两圆柱中任一个的平均谢尔特数总是小于单个圆柱的。并给出了简化计算的条件与公式。

| Abstract: | Convective heat transfer across two cylinders in line is numerically investigated in the range of Peclet numbers from 0 to 50 for four different gap sizes. The results show that heat transfer characteristics have an influence on each other between the two cylinders and the influence becomes more sensitive with the decrease of gap sizes. Each average Nusselt number of the two cylinders is always smaller than that of a single cylinder. The conditions and formulae are given for simplication. |
