Intensified gas-solids contact in the fuel reactor of chemical looping combustion systems can be a key issue for achieving the necessary gas-phase conversion rates. Wedge-shaped rings were designed and installed in the fuel reactor of a cold flow model for fluid dynamic testing. These internals are meant to reduce the typical radial and axial solids concentration non-uniformity. It is shown, that more solids are present in the upper regions of the riser when in-ternals are used. Additionally, increase of the solids elutriation rate from the riser was found
