Turbulent Dynamics of Particle-laden Pipeline Flow
University of Maryland, USA
Multiphase, multicomponent flow is a common occurrence in oil transport and handling processes.
This regime of multiphase flow is a relatively poorly studied flow condition, and one largely based on
empirical fits to limited data. As a start on a more complete understanding, two-phase experiments
consisting of solid/liquid suspensions have been conducted to study the detailed turbulent flow behavior of
two-phase multicomponent flow (liquid/solid), and their resulting coupling effect on the equivalent singlephase
flow. Advanced quantitative imaging techniques of particle image velocimetry (PIV) for multiphase
systems has been used to provide instantaneous measures of the constituent phase geometry, volume
fraction, and velocity, which can then be averaged to examine the detailed turbulence properties of the
flow and the important inter-phase transport terms in the equations of motion describing the system.
Results of these measurements are used to explain the suspended concentration of particulates and their
effect on the effective wall stress.
