A Study of the Factors Affecting Transporting Solid— Liquid Suspension through Pipelines ()
Abstract
An experimental investigation was
carried out on the transport of solid liquid mixture through pipelines. The
principal aim of this was to study how to transport slurries through pipeline
systems. The experimental tests include measurements of main parameters affecting transport of
solid liquid mixture, like sand slurry and mud slurry. These parameters are
deduced by applying non-dimensional approach, which includes Reynolds number, Froude number, concentration,
specific gravity, and ratio of particle to pipe diameter. Preliminary results include the following
general trends: 1) Increasing input concentration increases the
pressure gradient, whereas decreases the efficiency of solid transport; 2) As specific gravity of solid material increases,
the pressure gradient increases and the efficiency of transport decreases; 3) As mixture velocity increases, the efficiency of
transport increases; 4) Solids with fine grain
size are preferred than with coarse grain size from the view points of pressure
gradient and efficiency of transport. Also,
the present experimental data has been compared with the correlations developed
before by different authors. Such correlations relate the pressure gradient to flow velocity, specific
gravity, and efficiency of transport to grain size of solid material, and input
solid concentration.
