Summary

Laminar swirl flow of a viscous fluid having intermediate Prandtl number range was considered. The swirl was generated by regularly spaced twisted-tape elements with single twist in the tape module and connected by thin circular rods. The tape-width and the rod diameter were both varied. The effect of higher-than-zero phase angle between consecutive tape elements has been studied. Reynolds number, Prandtl number, twist ratio, space ratio, tape-width, rod-diameter and phase angle govern the characteristics.
