... (HDQ) and eigenvalue analysis method are used to solve the pipe governing equation. The effects of solid particle concentration and size, pipe mass ratio and gravity coefficient are discussed. These parameters on pipe stability, critical velocity and critical frequency are analyzed. INTRODUCTION...

...). It is a new attempt to use MPS method to simulate liquid flow in pipeline, and DEM method is a particle numerical method based on discontinuous medium assumption, which is especially suitable for solving solid particles in mixed transportation by averaging ore shape with spherically shaped solid particles...

... installation into particle feeding lines (Muschelknautz et al., 2011). The compact size means smaller volume and lower residence time of solid particles or gases in a separator. And one-directional particle separation is available to reduce pressure loss between an inlet and outlet. In the current study, we...

... ABSTRACT: An experimental and numerical study was carried out to study solidliquid mixture upward hydraulic transport of solid particles in vertical and inclined annuli with rotating inner cylinder. Lift forces acting on a fluidized particle plays a central role in many importance applications...

... varied from 0.2 m/s to 2.0 m/s under the actual drilling operational condition. Macroscopic behavior of solid particles, averaged flow rate, and particle rising velocity are observed. For both waater and CMC solutions, the higher the concentration of the solid particles are, the larger the pressure...
