本文根据传热学的基本原理,采用冷却单元计算法推导得到了一套完整的关于扁圆管单面贴壁冷却方式的理论计算方法。用这套计算方法不但可以确定壁面的温度工况,而且揭示了影响壁温工况的各种因素及其影响关系,为设计计算提供了依据。文中还介绍了为验证理论计算公式精确可靠程度而进行的近似模型试验情况。最后就扁圆管单面贴壁冷却方式提出了几点初步看法。 Based on the basic principle of heat transfer, this paper deduces a set of complete theoretical calculation method of the cooling method of single-sided adherent wall cooling by using the calculation method of cooling unit. This method can not only determine the temperature conditions of the wall, but also reveal the various factors that affect the condition of the wall temperature and their relationship, which provides the basis for the design and calculation. The paper also introduces the approximate model test for verifying the accuracy and reliability of the theoretical calculation formula. At last, the author put forward some preliminary opinions on the single-wall adherent cooling method of oblate tube.
