Abstract
The recirculation occurring at the junction of a zero flowrate pipe connected to a high Reynolds number (>1 million) flow piping system, may give rise to a corkscrew flow pattern extending along the dead leg, even though the geometry of the domain is symmetrical with respect to the plane including the axes of the two pipes. Parametric tests performed on a hydraulic mock-up made of Plexiglas, by means of laser Doppler velocimetry, with Reynolds number ranging from 1 to 7 millions, show that the Reynolds number affects directly the development and the intermittent characteristic of the swirl in the dead leg, that the phenomenon is very sensitive to geometric details of the junction which may reverse the rotation, whereas the influence of the upstream conditions is by comparison less significant.
