本文旨在更新振荡流蓄热器试验台数据给出的斯特林发动机蓄热室摩擦因数与换热的不同关联式。为此，使用雷诺数、摩擦因数、压降、努塞尔数和换热面积的通用方程组重新计算了数据。根据这些一般定义，可以将流动摩阻系数的关联式和努塞尔数关联式分别表示为一张曲线图和一张曲线图，从而很好地反映了它们的特点和它们之间的偏差，本文对此进行了讨论。
This paper is intended to update the overview of different correlations for the friction factor and heat transfer of Stirling engine regenerators given by the Oscillating-Flow Regenerator Test Rig data. For that purpose the data was recalculated using the general applicable set of equations for Reynolds number, friction factor, pressure drop, Nusselt number and heat transfer area. Based on these general definitions, the correlations can be shown in one plot for the flow friction factor and one plot for the Nusselt number, giving a good impression of their characteristics and the deviations among them, which are discussed in the body of this paper.
