| Abstract: | Saturated flow boiling heat transfer coefficients of ethane(R170)/propane(R290) binary mixtures at three different concentrations inside an 8 mm inner diameter horizontal tube have been measured.Influences of heat flux and mass flow on binary mixtures' heat transfer coefficients were analyzed.Four heat transfer calculation methods developed for binary mixture were chosen to compare with the experimental data.Among these,the Gungor-Wintcrton and Thome correlation and Zou correlation have relatively small pre... |
