Abstract

An aspect of the present invention relates to a device (10) for flow forcing of a fluid, the device comprising: a first electrode arrangement (A), in particular a set of dielectric barrier discharge plasma actuators or a set of corona discharge plasma actuators, the first electrode arrangement (A) comprising: a reference electrode (12) having a length extending along a first axis and a width extending along a second axis perpendicular to the first axis; a first array (14a) of electrodes (Ea) disposed at the reference electrode (12) and arranged substantially along the first axis; and wherein the reference electrode (12) is insulated from the first array (14a) and all electrodes of the first array (14a) are insulated from each other; wherein the device (10), in particular the first electrode arrangement (A), when the electrodes (Ea) of the first array and/or the reference electrode (12) are supplied with a plurality of voltage signals, is configured to generate, in the fluid: a stationary fluid wave being aligned substantially along the first axis, oscillating substantially along the second axis and being stationary sub-stantially along the first axis; or a travelling fluid wave being aligned substantially along the first axis, oscillating substantially along the second axis and propagating substan-tially along the first axis. Further aspects of the present invention relate to a method for flow forcing of a fluid and a use of said device for flow forcing of a fluid.
