| Research Abstract |
Themechanismsofmass transferand themethods for drag reduction,in two-phase flow systems as are seen in oil pipelines, were examined using numerical simulation with a high degree of accuracy. The influences of particle inertia, gravity,particle-wall interaction and gas turbulence on the mechanisms of dispersions ofparticles and of droplets in nonhomogeneous gas turbulent flow were presented. Themeasurements of the turbophoretic velocities and the balances of the mean body forcesshowed that the damping of the fluid turbulence is due to the attenuation of the large-scale fluid turbulence structures, that is caused by the disperse phase.
