A new drag correlation from fully resolved simulations of flow past monodisperse static arrays of spheres.

Fully resolved simulations of flow past fixed assemblies of monodisperse spheres in face-centered-cubic array or random configurations, are performed using an iterative immersed boundary method. A methodology has been applied such that the computed gas-solid force is almost independent of the grid resolution. Simulations extend the previously similar studies to a wider range of solids volume fraction ( [ABSTRACT FROM AUTHOR]
