Аэродинамические характеристики поперечно-омываемых пучков труб с просечным спирально-ленточным оребрением

Abstract

The results of the experimental research of the aerodynamic resistance of cross-flow in-line tube banks with cut spiral fins in the region of changing geometrical values of bank and tubes H/F=8,787...13,713, S₁/S₂=0,662...1,633 and of Reynolds number 5·10³...3,6·10⁴ are presented. By generalized experimental research’s foundation there were getting a dependence for a calculation of resistance banks in pointed limits of change of certain parameters.
