These materials are available in large quantities and with a large diversity considering dimensions – cell diameters from µm to mm – and nature – metals, ceramics, plastic,.. . Solid open-cell foams are highly porous (from 60 to 97 %) monolithic media with a continuous cross-linked strut network resulting in a quite irregular structure. These structures enable a considerable reduction of pressure drop combined to very high geometrical specific surface areas. Fluid flow can proceed in all the directions resulting in a good radial mixing.
