Numerical Analysis of Dense Phase Liquid-Solid Flow in a Horizontal Pipe,ations of continuity and motion. The calculated results showed the characteristic flow patterns of liquid-solid systems, such as flows with a moving bed or a deposit. The relation between the fluid velocity and the flow pattern agreed with the experimental results of sediment transport.

A Non-Axisymmetric Pattern Selection Problem in Core-Annular Flow,to see whether one of these waves will be stable to small amplitude perturbations. Sample situations for down-flow are discussed. The corkscrews tend to be preferred when the annulus is narrow, while snakes are more likely when the annulus is wide.

Numerical Simulation of Particle Motion in Viscoelastic Fluids,namic forces and moments exerted by the suspending fluid. The developed package is able to simulate the motion of particles in several popular models of non-Newtonian viscoelastic fluids..This package was used to study the mechanisms of chaining of sedimenting particles in a viscoelastic fluid and detachment of the particles from the chain.

Thoughts Old and New on Moving Contact Lines,ian fluid) mechanics. This arises because traditionally it is assumed that, even at a perfectly smooth plane solid surface, there is no velocity discontinuity between fluid and solid; this is the celebrated no-slip assumption.

Paraffin Deposition Phenomena in Crude Oil Pipelines,h are not well understood for either single phase or multiphase flow conditions. Once started, paraffin deposition can continue until significant reductions occur in the pipe cross-sectional area available for flow, sometimes resulting in total blockage.

Migrational Instability in Shear-Thinning Suspensions,ely to a two-phase structure, involving particle-rich regions in dynamic equilibrium with particle-depleted regions, which in the case of pipe flow should result in a “core-annular” structure, with viscous core surrounded by a less viscous lubricating layer.
