Two-phase flow boiling pressure drop experiment was conducted to observe its
characteristics and to develop a new correlation of void fraction based on the
separated model. Investigation is completed on the natural refrigerant R-290
(propane) in a horizontal circular tube with a 7.6 mm inner diameter under
experimental conditions of 3.7 to 9.6 ï‚°C saturation temperature, 10 to 25 kW/m2 heat
flux, and 185 to 445 kg/m2s mass flux. The present experimental data was used to
obtain the calculated void fraction which then was compared to the predicted
void fraction with 31 existing correlations. A new void fraction correlation for
predicting two-phase flow boiling pressure drop, as a function of Reynolds numbers,
was proposed. The measured pressure drop was compared to the predicted
pressure drop with some existing pressure drop models that use the newly
developed void fraction model. The homogeneous model of void fraction showed
the best prediction with 2% deviation.
