This study investigates the characteristics of the secondary motion in swirling flows induced by 180 degree twisted tapes in circular pipes. The characteristics of the flow are analyzed using Laser Doppler Velocimetry (LDV) measurements, flow visualizations and numerical simulations. Helical vortices are identified for the first time downstream of twisted tapes swirlers, explaining the apparent counter-rotating flow observed in previous studies of swirling flows. Helical vortices occur often in nature but the vortices described here are the first stable helical vortices ever observed. Their st...
