S. Yapici et al., ELECTROCHEMICAL STUDY OF MASS-TRANSFER IN DECAYING ANNULAR SWIRL FLOW.2. CORRELATION OF MASS-TRANSFER DATA, Journal of Applied Electrochemistry, 25(1), 1995, pp. 15-22
This paper presents correlations of local mass transfer at the inner r
od and the outer wall in annular decaying swirl flow generated by axia
l vane swirl generators. Four swirl generators with vane angles in the
range 15-60-degrees to the duct axis were used and experiments were c
arried out in a Reynolds number range 3300-50000 and at a Schmidt numb
er 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 pip
e. Comparison is made with heat transfer data for work with a similar
entry configuration.
