... with scintillation counters. The measured passage of a solid particle through the measurement cross-sections allowed to determine the time of passage between the cross-sections. Having determined the time of passage of the particle between the cross-sections and knowing the distance between them allowed to determine...

... transportation necessary is to know the minimal velocity of flow, which allow the solid particles to lift up. General rule says that velocity of flow must be higher than fall velocity of particles in mixture (or the largest particles in case of variously graded material). Fall velocity of a single solid particle...

... ABSTRACT: An experimental investigation is carried out to study two-phase vertically upward hydraulic transport of solid particles by water and non-Newtonian fluids in a slim hole concentric annulus with rotation of the inner cylinder. Studying the rheology of particulate suspensions...

... solid particles from the sea water. The suspended solids are separated from the liquid due to the centrifugal force induced inside the hydrocyclone (Fig. 2). The bigger and heavier particles flows out along with the hydrocyclone wall towards the underflow pipe, while the smaller and lighter ones change...

... in a vertical pipeline is different than in a horizontal pipeline. In upward now of large and heavy solid particles their velocity diners from the water velocity and the available slip velocity is an important feature of the now. The prediction of turbulent flow headloss for such mixtures has remained one...

... that the increase of discharged volume fraction and diameter of the solid particles causes the pressure drop in the hose and the increase of the minimum velocity to transport the solid particles in the identical flexible hose. In the case of the solid-liquid two-phase mixture velocity more than 1.5 mlsec, the more...

The experimental results show that the pressure drop and hydraulic gradient in the tube increase because the in-situ volume fraction of solid particles in the tube increases when the discharge volume...
