Abstract: To understand the specific role of hydrocyclone in hydraulic transportation, a horizontal straight
pipeline was used to experimentally test the hydraulic characteristics of hydrocyclone in its motion process.
Model test and theoretical analysis were used in this study to examine the behaviors of hydrocyclone with
different widths and different angles of guide vanes. It is shown that a larger angle of guide vanes leads to
lower axial velocity, greater circumferential velocity, and greater absolute value of radial velocity at test
section. The wider the guide vanes, the smaller the axial velocity and the greater the circumferential velocity
at test section, and the greater the radial velocity in tube core. When the flow rate is increased, the axial
velocity at test section increases, but the trends of changes in circumferential and radial velocities depend on
the angle of guide vanes.
