Comparative CFD Analysis of Heterogeneous Gas–Solid Flow in a Countercurrent Downer Reactor
TL;DR: In this paper, a comparative study was performed to study the effect of input parameters on the hydrodynamics of gas-solid flow in a countercurrent downer reactor, and it was concluded that the input parameters of the Eulerian model, including restitution coefficients, specularity coefficient, and drag correlation, have a major effect on the bed hydrogynamics.

Frictional–collisional constitutive relations for granular materials, with application to plane shearing
P. C. Johnson,R. Jackson +1 more
TL;DR: In this article, the authors propose constitutive relations and boundary conditions for plane shear of a cohesionless granular material between infinite horizontal plates, and show that not all the material between the plates participates in shearing and the solutions for the shearing material are coupled to a yield condition for the non-shearing material to give a complete solution of the problem.
