چکیده انگلیسی
A prediction model of CO2 condensation heat transfer coefficients was developed. The flow patterns in the present model were predicted by the Soliman model. The existing Thome et al. model was applied to predict heat transfer coefficients for the wavy-intermittent and annular flow. The modified Dittus-Boelter equation was utilized for the mist flow. Heat transfer coefficients in the annular-mist flow were calculated from the combination of models for the annular and the mist flow with the ratio of We number. The mean deviation of the present model with the experimental data of 589 points from seven different sources was 44.8%. The present model showed improved predictability compared to the existing models under high mass flux and high condensation temperature conditions, and with a small diameter tube.
