摘要

Turbulent wall friction and forced convection heat transfer in a water-cooled trapezoidal channel were experi- mentlal investigated. The parameter ranges were: Reynolds number=10~4-8.6×10~4, and Prandtl number=2.2-5.5. The channel hydraulic diameter was 1.14 cm, and its total and heated lengths were 139.4 and 60.9 cm, respectively. The Colebrook correlation predicted the unheated channel friction factors well.
