Flow structure of coarse-grained slurry in a horizontal pipe

Original language description

The flow behaviour of coarse-grained slurry depends on particle size, shape, density and concentration,and on the density and rheological properties of the carrier liquid. The present paper describes the results of an experimental investigation and flowvisualisation of model coarse-grained particle-water mixtures in a closed pipe loop with smooth stainless steel pipes of inner diameter 36 mm. Glass balls and washed graded pebble gravel of mean diameter d50 = 6 mm were used as model coarse-grained material. The effect of slurry velocity and particle concentration on the slurry flow behaviour and pressure drop in the turbulent regime was evaluated. Particle distribution in the pipe cross-section and motion of particles along the pipe invert, particle saltation and particle conveying in the carrier liquid were investigated in a transparent pipe viewing section and motion of individual particles was described. Velocity profiles of the carrier liquid and conveyed particles were determined.
