RT Journal Article ID 7db47c2c1debcf03 A1 Orlu, Ramis A1 Alfredsson, P. Henrik T1 Passive Scalar Flux Measurements in the Near-Field Region of a Swirling Jet JF Heat Transfer Research JO HTR YR 2008 FD 2008-09-20 VO 39 IS 7 SP 597 OP 607 AB The present experimental investigation is devoted to the heat flux characteristics of a passive scalar in the near-field region of a swirling jet issuing from a fully developed axially rotating pipe flow. A combined X-wire and cold-wire probe made it possible to access the instantaneous streamwise and azimuthal velocity components as well as the temperature simultaneously. Results indicate that the addition of swirl increases the integral scales and entrainment and thereby the streamwise passive scalar flux and shortens the distance and hence time needed to mix the jet with the ambient air.
