For more than 20 years, the Saskatchewan Research Council’s PipeFlow model has been used by companies across the globe to predict pressure losses and minimum operating velocities (‘deposition velocities’) for the pipeline transport of heterogeneous (settling) slurries. The success of this semi-mechanistic, phenomenological model comes from the fact that the friction loss contributions of the dispersed, coarse particle phase are accounted for in a physically meaningful way. The focus of this study is on the need to make accurate off-line slurry characterization measurements to obtain accurate predictions of slurry flow behavior. The results of a number of slurry pipeline tests conducted under controlled conditions are presented. These results clearly demonstrate that, in addition to accurate measurements of particle size distribution and density, proper characterization of the following parameters is also critical: carrier fluid viscosity, settled bed coarse particle concentration, particle drag coefficient / particle terminal settling velocity, and the coefficient of friction between the particles and the pipe wall.© 2013 ASME |
