Abstract
Mass transfer measurements at both the inner and outer walls in decaying swirl flow in an annular duct have been carried out using the electrochemical limiting diffusion current technique. Swirl was generated using axial guide-vanes with vane angles between 15–67° to the duct axis. Pressure measurements at the outer wall were also made to enable estimation of the energy cost of mass transfer enhancement. Overall correlation of mass transfer at the outer wall for a representative length of test section in terms of the energy required to impart swirl to the flow can be expressed as Sh Sc -1/3 = 0.0251 (1 + tan θ w )-0.18 X 0.316 for the Reynolds number range 3000– 50000, where θ w is the vane angle at the wall and X is an energy dissipation parameter.
