Modified liquid entrainment fraction correlation for varying pipe orientation and system pressure

• Proposal of correction factor to Cioncolini and Thome (2012) correlation.
• Correction factor accounts for the effect of pipe orientation and high system pressure on liquid entrainment fraction.
• Proposed modification predicts more than 80% of data within ±50% error in horizontal and upward pipe inclinations.
• Proposed modification predicts more than 90% of data at high system pressure within ±30% error.
