摘要
分别在强制对流和自然对流两种传热条件下 ,对变对流传热系数和变物性时管道保温层的经济厚度进行了分析和计算 ,给出了有关计算式 ,并把结果与常对流传热系数时管道保温层经济厚度的计算结果进行了比较 。
On the condition of forced and natural convection, the economical thickness for pipe insulation with variable convective heat transfer coefficient and properties of fluid is investigated analytically and corresponding calculating expressions of economical thickness are obtained. In the meantime, the results are compared with that of constant convective heat transfer coefficient and provided reference for design of pipe insulation.
