Abstract
A device (1, 100) for controlling a flow of a gaseous fluid is disclosed. The device comprises a first electrode (10, 110) and a second electrode (20, 120) offset from the first electrode in a downstream direction of the flow. The electrodes are connectable to a voltage source. A thermally conducting flange (30) is arranged to extend in a plane parallel to a direction of the flow and adapted to dissipate heat from the gaseous fluid. At least a portion of the first electrode has a maximum height (h1) in a direction parallel to a direction of the flow and a maximum width (w1) in a direction orthogonal to the direction of the flow, wherein said maximum height is larger than said maximum width so as to improve the pumping efficiency of the device. A method for manufacturing the device, and a method for controlling a fluid flow by means of such device, is also disclosed.
