    摘要： The invention relates to a device for treating a gas flow (22), in particular an exhaust gas flow of in internal combustion engine, comprising at least one radial chamber (3) which can be flown through radially by the gas flow (22), which extends essentially radially from a central area (2) to an outer collection chamber (5). Said radial chamber (3) is defined by a first (1) and a second (2) essentially disk-shaped wall and a plurality of electrodes (11) directed into the radial chamber (3) protrude from the first wall (1). The first (1) and second (2) disk-shaped walls extend preferably parallel. The first disk-shaped wall (1) is preferably formed from an electrically insulating material (13) with electrically conductive electrodes (11) secured therein, which are electrically connected under each other by electric conductors (12) extending in or on the electrically conductive material (11) Two or more radial chambers (3) extending parallel can be arranged axially on each other about a central area (4). The claimed device can effectively treat an exhaust gas with an electric field for ionizing or generating a plasma, in the flow direction, in relatively short production length. Electric fields extending transversely to the direction of flow generate new possibilities in the selection of various parameters in the treatment device

    摘要： The method according to the invention for evaporating a predeterminable volume of a fluid comprises the following steps: a) successive addition of at least one first partial volume at a first volume adding rate (17) and at least one predeterminable second partial volume that is different from the first partial volume, at a second volume adding rate (17) to a supply line (3); b) at least partial evaporating of the partial volumes such that a vapor film is formed between the partial volumes and a wall of the supply line (3); c) conveying the partial volumes through the supply line (3) to an evaporator surface (5); and d) applying the partial volumes to a region of the evaporator surface (5), the position of which is varied as a function of at least one of the following parameters: i) the mass of the corresponding partial volume and ii) the volume adding rate (17) of the corresponding partial volume. The method according to the invention and the device (1) according to the invention advantageously permit an evaporation of a fluid, particularly of a urea/water solution, in a manner that is as effective as possible. The utilization of the highest possible proportion of evaporator surfaces is achieved by the mass and/or volume addition rate-dependent distribution of the impingement surfaces on the evaporator surface (5). For this purpose, a heating strategy is advantageously employed in the region of the supply line (3) that ensures that the Leidenfrost effect occurs when the individual partial volumes are added. In this manner, a distribution that is as even as possible can be achieved using a corresponding configuration of the geometry of the evaporator channel (4).
