METHOD AND APPARATUS FOR FLOW CONTROL OF A GAS

摘要

In a method for flow control of a gas with means of Electrohydrodynamic (EHD) actuating the flow near some dimple-like structures at walls the dimple-like structure in the walls is used for generating a turbulance flow of the gases and the electrohydrodynamic (EHD) actuation of the flow is effected by means of an electrical gas discharge generated between at least two electrodes placed near to or overlapping the dimple-like structure. In an Apparatus for the method, with at least two electrodes (13, 14) for EHD-actuation one of the electrodes (13, 14) is located flow-down of the dimple (12) and the other one is located around the bottom of the dimple (12).
