Droplet entrainment measurements under high-pressure two-phase low-liquid loading flow in slightly inclined pipes

This paper presents new experimental data for droplet entrainment measurements under low-liquid loading two-phase flow. Liquid and gas flow rates are representative of the flow in wet gas/condensate pipelines under stratified and annular flow patterns. The novelty in the experimental conditions are the high-pressure (2.76 MPa), large diameter pipe (0.155 m) and inclination from the horizontal (2 degrees). The used fluids are Isopar-L oil and Nitrogen gas. Data are presented as a function of system pressure, liquid and gas superficial velocities, and dimensionless numbers. Comparisons of the new data with previous models are also provided.
