CFD predictions using the URANS equations have been compared to phase-averaged and instantaneous PIV pulsating flow fields in a planar diffuser upstream of a catalyst monolith. URANS qualitatively capture the velocity and vorticity fields, in particular the spatial and temporal evolution of the main...
