摘要: This paper quantifies the effect of mass transfer (suction) on wall friction for turbulent vapour flow inside ducts during condensation. Correlations are presented factor in terms suction rate, and utilized estimating frictional pressure change condenser tubes. These correlations derived from numerical integration velocity profile through boundary layer, based Van Driest model Prandtl mixing length. Predictions drop condensation steam an air-cooled duct correspond to within ±5% experimental measurements.
