Numerical study of rope formation and dispersion of non-spherical particles during pneumatic conveying in a pipe bend

Influence of flow direction change on the particle segregation in horizontal pipes

“…The most common side effects caused by the phenomenon of particle segregation, in addition to erosion and pulsation (Wydrych et al, 2017, Anweiler et al, 2004 may include a change in operations conditions in industrial installations and often their deterioration (Akili et al, 2001, Lain et al, 2012. The formation of particle rope is a problem, particularly with non-spherical particles (Kruggel-Emden et al, 2014). It was also compared both, experimental and numerical research of pulverized coal particles conveying in the horizontal channel (Akili et al, 2005).…”

Comparative study on mesh-based and mesh-less coupled CFD-DEM methods to model particle-laden flow

“…Since then, a lot of investigations for the improvement of various aspects of this coupling were conducted [3,5]. A wide range of applications such as fluidized beds [9], cyclones [10], screening [11], pipeline flow [12], particle coating processes [13], pneumatic particle transport [14] and others have been discussed in the scientific literature. It could be concluded, that DEM techniques coupled with mesh-based methods are widely recognized as state of the art in current research.…”

Simulation of inertial behavior of dilute particle flow in horizontal channel with Eulerian method of velocity-reassociated quadrature-based method of moments

“…[1,2,3,4] The conveying systems are capable of transporting almost any kind of material. In practice, the conveying distance of the single stage of the system can reach 1.5 km for most applications.…”
