“…3) and are characterized by a large pressure drop that is caused by a decrease in the discharge section. In the ascending part of the flexible pipe, a layer of solids located at the bottom of the pipe and that is flowing backwards is even observed for these low velocities, as already observed by Yamaguchi et al [17] (see top left picture in Fig. 3 that is taken at V mix = 0.9 m.s −1 ).…”

“…In the case of the transport of large solid particles by a carrying liquid, several intermittent, stratified and dispersed regimes are observed in horizontal and inclined flows [1,2,4,17]. For the specific case of vertical ascending flows, though plug or slug flows are observed in the pneumatic transport of small particles [18], to the best of our knowledge only dispersed regimes are observed for the hydraulic transport of large (d p 1 mm) and massive (s 1.5) particles [2,[9][10][11].…”

“…However, in horizontal, and a fortiori in geometries in S-shape, there are few models [1][2][3][4][12][13][14][15] and the effects of specific mass and more specifically of very large particle size have not been systematically explored. One major difficulty in the case of transport of large particles and high specific mass comes from the various flow regimes that may be observed [1,2,4,12,13,16,17]: when the speed of transportation increases, several transitions arise from regimes with a layer of solids at the bottom of the pipe that is at rest or that flows backwards in inclined pipes [13,16,17] to regimes with a moving bed and eventually to heterogeneous and pseudo-homogeneous suspensions at high mixture velocities.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. AbstractThis article presents an experimental study of the hydraulic transport of very large solid particles (above 5 mm) in an horizontal pipe. Two specific masses are used for the solids. The solids are spheres that are large with respect to the diameter of the pipe (5, 10 and 15%) or real stones of arbitrary shapes but constant specific mass and a size distribution similar to the tested spherical beads. Finally, mixtures of size and / or specific mass are studied. The regimes are characterized with differential pressure measurements and visualizations. The results are compared to empirical models based on dimensionless numbers, together with 1D models that are based on mass and momentum balance. A model for the transport of large particles in vertical pipes is also proposed and tested on data available in the Literature, in order to compare the trends that are observed in the present experiments in a horizontal pipe to the trends predicted for a vertical pipe. The results show that the grain size and specific mass have a strong effect on the transition point between regimes with a stationary bed and dispersed flows. The pressure drops are moreover smaller for large particles in the horizontal part contrary to what occurs for vertical pipes, and to the predictions of the empirical correlations.

A framework is developed to integrate MFiX (Multiphase Flow with Interphase eXchanges) with advanced linear solvers in Trilinos. MFiX is a widely used open source general purpose multiphase solver developed by National Energy Technology Laboratories and written in Fortran. Trilinos is an objected-oriented open source software development platform from Sandia National Laboratories for solving large scale multiphysics problems. The framework handles the different data structures in Fortran and C++ and exchanges the information from MFiX to Trilinos and vice versa. The integrated solver, called MFiX-Trilinos hereafter, provides next-generation computational capabilities including scalable linear solvers for distributed memory massively parallel computers. In this paper, the solution from the standard linear solvers in MFiX-Trilinos is validated against the same from MFiX for 2D and 3D fluidized bed problems. The standard iterative solvers considered in this work are Bi-Conjugate Gradient Stabilized (BiCGStab) and Generalized minimal residual methods (GMRES) as the matrix is non-symmetric in nature. The stopping criterion set for the iterative solvers is same. It is observed that the solution from the integrated solver and MFiX is in good agreement.
