1. A method for influencing a fluid flow in a fluid line having a wall, a honeycomb body with a fluid inlet side and a fluid outlet side is arranged in the fluid line, the honeycomb body has a honeycomb structure with a cross-sectional area and with ducts through which the fluid flow can pass from the fluid inlet side to the fluid outlet side, the honeycomb body has an outer boundary, the honeycomb structure has an encircling outer zone close to the boundary and has a central zone arranged within the outer zone, the outer zone accounts for at most 70% of the cross-sectional area, the method comprising:
providing the fluid flow upstream of the honeycomb body; introducing the fluid flow into the honeycomb body via the fluid inlet side, wherein, at the fluid inlet side, an average first inflow speed of the fluid flow in the outer zone close to the boundary is lower than an average second inflow speed of the fluid flow in the central zone; and at least partially diverting the fluid flow in an outward radial direction, such that, at the fluid outlet side, an average first outflow speed of the fluid flow in at least one subregion of the outer zone close to the boundary is at least 20% higher than an average second outflow speed of the fluid flow in the central zone. |
