We study a high-viscosity two-phase flow through an analysis of the corresponding pressure signals. In particular, we investigate the flow of a glycerin–air mixture moving through a horizontal pipeline with a U-section installed midway along the pipe. Different combinations of liquid and air mass flow rates are experimentally tested. Then, we examine the moments of the statistical distributions obtained from the resulting pressure time series, in order to highlight the significant dynamical traits of the flow. Finally, we propose a novel correlation with two dimensionless parameters: the Euler number and a mass-flow-rate ratio to predict the pressure gradient in high-viscosity two-phase flow. Distinctive variations of the pressure gradients are observed in each section of the pipeline, which suggest that the local flow dynamics must not be disregarded in favor of global considerations.

Pipe Inclination

An experimental study of the inclination angle (±2° from horizontal) effects on high viscosity oil and gas two-phase flow has been conducted, and the available multiphase flow models/correlations have been evaluated using the acquired data. The effect of pipe inclination on the slug flow characteristics of highly viscous oil-gas two-phase flow was studied based on 1,040 data points covering a wide range of experimental conditions and liquid viscosities in a 50.8-mm-ID pipe at 2° downward and upward inclinations from horizontal. The oil viscosity ranged from 155 cP to 587 cP. Superficial liquid and gas velocities varied from 0.1 m/s to 0.8 m/s and from 0.1 m/s to 5 m/s, respectively. The basic two-phase flow parameters and slug flow characteristics have been analyzed and compared with the past studies conducted for near horizontal pipes.
