Abstract

This paper presents correlations of local mass transfer at the inner rod and the outer wall in annular decaying swirl flow generated by axial vane swirl generators. Four swirl generators with vane angles in the range 15-60-degrees to the duct axis were used and experiments were carried out in a Reynolds number range 3300-50000 and at a Schmidt number of 1650. The results were correlated in the general form Sh(x) = 0.0204 Re(x)0.86 (1 + tan theta(i))0.53 Sc1/3, for the inner rod, and Sh(x) = 0.0224 Re(x)0.86 (1 + tan theta(o))0.55 Sc1/3, for the outer pipe. Comparison is made with heat transfer data for work with a similar entry configuration.
