Influence of particle-specific gravity and particle shape on the averaged axial velocity of nearly neutrally buoyant particles in horizontal pipes
Authors:S. Liu  P. J. Fryer  J. P. Pain
Abstract:This paper presents an experimental study on the velocities of single, nearly neutrally buoyant particles in water in horizontal flows. Particle specific gravity was found to have a strong effect on the particle velocity. The modified particle Froude number was found to be an effective parameter to reflect the effect of density. A force-balance model has been developed that includes the effects of particle specific gravity and particle shape.
Keywords:two-phase flow  flow of nearly neutrally buoyant particles
