摘要

以横肋管为典型人工糙管

空气为试验介质

恒热流操作

进行湍流传热时径向温度分布和传热特性的测定

试验Re为20000～70000.所得湍流核心区温度分布可以对数分布律和温度亏损律表示

式中常数与粗糙几何参数有关.由测得的温度分布和速度分布计算了湍流粘度和湍流导温系数.此外

还进行了温度脉动特性的测定.传热系数测定结果表明

人工粗糙管比光滑管强化150%～300%

传热膜系数可用简单关联式估算Nu/Nu_s=1+26(k/d)~(0.49)(S/K)~(-0.46)式中Nu_s=0.022Re~(0.8)Pr~(0.5)

Abstract

Radial temperature profiles and heat transfer coefficients were measured for the turbulent flow of air in a smooth pipe and repeated-rib pipes with 0.01
