PCT No. PCT/SE86/00548 Sec. 371 Date May 27, 1988 Sec. 102(e) Date May 27, 1988 PCT Filed Dec. 2, 1986 PCT Pub. No. WO87/04020 PCT Pub. Date Jul. 2, 1987.An arrangement for transporting air with the aid of an electric ion wind comprises a corona electrode (K) and a target electrode (M) located downstream of the corona electrode. A d.c. voltage source (3) has its terminals connected to the corona electrode and the target electrode, respectively, so that a corona discharge is generated at the corona electrode. The corona electrode (K) includes one or more wirelike electrode elements (4) located adjacent the symmetry axis of the air-flow path (1) and having, as seen in a direction perpendicular to the symmetry axis, an extension which is substantially much smaller than the cross dimension of the airflow path. The wirelike electrode elements (4) lack free, unattached ends at which the field strength exceeds the field strength at the peripheral surface of the electrode elements, thereby avoiding punctiform corona-discharge concentrations and confining the corona discharge to the peripheral surface of the electrode elements. |
