The results obtained show an excellent match against experimental data in both single-phase and multiphase flow configurations and for either deposition or entrainment conditions. The proposed methodology is deemed to contribute to an efficient sand management strategy because...

... ABSTRACT An experimental investigation has been carried out to analyze the effect of the diameter on two-phase flows in vertical large-diameter pipes. This study generated and gathered experimental data for diameters ranging from 19 to 297 mm. The working fluids for the experimental database...
