“…By obtaining local Eulerian temporal energy spectra above the base of a vessel using LES simulations mimicking actual physical solid–liquid mixing experiments, the local time scale of the turbulent eddies and their respective energies are available to compare with the particle response time. The technique of obtaining and processing Eularian energy spectra from LES is detailed in Giacomelli et al 11 The instantaneous fluctuating component of the resolved velocity field is extracted at discrete sampling locations at a given sampling frequency. The resolved velocity field being three‐dimensional, the energy spectra are computed in the time domain as the sampling points are fixed.…”

“…The model geometry was identical to the physical system from which these impeller speeds were determined and therefore the information given in Tables 1–3 can be referenced. The software used to complete the modeling was M‐Star CFD which uses the Lattice‐Boltzmann technique to solve the Navier–Stokes equations 11 . The subgrid scale viscosity was computed according to the Smagorinsky model with the Smagorinsky constant, C s , set to 0.1.…”
