This study proposes a method for approximating the fully resolved flow through a monodisperse array of spherical particles using only the locations of the particles and the volume-averaged Reynolds number, both of which are available in Euler-Lagrange (EL) simulations. To achieve this, we first determine a superposable wake (SW) which best captures the behavior of direct numerical simulations (DNS). By adding the SW for all the particles, the pseudo-turbulence caused by the perturbed flow around a distribution of particles in an EL simulation can be approximated. A Reynolds stress model is then developed for use in an Euler-Lagrange framework. The range of Reynolds numbers and particle volume fractions considered in this study are 0.3≤Re≤173 and 0.11≤ϕ≤0.45 accordingly.
