抄録

The interfacial friction was investigated for high-pressure (3 to 9MPa) steam/waterstratified-wavy flow, using the TPTF experimental data for 4 and 8-inch diameter horizontalpipe test sections. The interfacial waves observed in the stratified-wavy flow regime with void fractions typically<-0.6, became larger in r.m.s. amplitude and more irregular in both amplitude and wave length, as the transition boundary to slug flow was approached. A correlation to predict the interfacial friction factor has been obtained for the stratified-wavy flows including the vicinity of the transition boundary to slug flow. The correlation is based on two nondimensional parameters related to the interfacial wave generation by the Kelvin-Helmholtzinstability, and correlates the TPTF data taken under different pipe diameters and pressures.
