This paper deals with air flow around the inner pipe in annular space of a double-pipe, induced by corona discharge.A discharge electrode, made of a thin wire of 0.14 mm in diameter, is set in the annular space, in parallel to each axis of both pipes, and at the same and shortest distance from the internal surface of the outer pipe and the external surface of the inner pipe, which are used as collecting electrodes. As the external surface of the inner pipe approaches to the internal surface of the outer pipe keeping above geometric condition, circulating flow around the inner pipe is observed. Details of the flow, such as the relation between the inner pipe position and the pattern of flow are made clear by use of visualization technique and by measurement of flow velocity.
