最近对计算管道中恒定属性流体的传热系数的方程进行了修改，以关联可变属性数据。相关方程具有方便的形式，适用于液体和气体，将 0· 1< Pr< 10 4 与 10 4< Re< 10 6 的 10% 以内的常数属性结果关联起来，将 0· 7< Pr< 75 与 10 000< Re< 506 000 的 20% 以内的可变属性数据关联起来。该方程与 Sieder-Tate 方程进行了比较对于液体以及气体和液体的两个 Petukhov 方程。提出了向可变特性液态金属传热的方程。
A recent equation for calculating heat-transfer coefficients to constant property fluids in pipes is modified to correlate variable property data. The correlating equation is of convenient form, applies to both liquids and gases, correlates constant property results within 10 per cent for 0· 1< Pr< 10 4 with 10 4< Re< 10 6, and correlates variable property data within 20 per cent for 0· 7< Pr< 75 with 10 000< Re< 506 000. The equation is compared with the Sieder-Tate equation for liquids and the two equations of Petukhov for gases and liquids. Equations for heat transfer to variable property liquid metals are suggested.
