چکیده مقاله
In this research work, a new developing two-phase frictional pressure drop model based on adiabatic and condensation experimental data has been presented. In recent years, several two-phase friction pressure drop correlations in mini/micro channels were presented, but still the lack of accurate models for designing such systems are exist. The frictional pressure drop of 3500 experimental data points of mini/micro channels, having hydraulic diameters ranges from 0.0695 to 6.22 mm, mass flux rating from 4.0 to 8528 kg/m2 s, with different working fluids is collected from reliable experimental data sources. Recent two-phase frictional pressure drop correlations reviewed and compared with the experimental data sets. A new Lockhart–Martinelli type correlation, with some modifications, is proposed to evaluate the frictional pressure drop experimental data. The results showed that the new model can predict the two-phase frictional pressure drop for adiabatic and condensing mini/micro-channel flows appropriately in comparison of other models used in this work.
