I. Nirdosh et Gh. Sedahmed, NATURAL-CONVECTION MASS-TRANSFER INSIDE HORIZONTAL SQUARE DUCTS, Chemical engineering communications, 130, 1994, pp. 193-201
Rates of free convection mass transfer inside horizontal square ducts
were measured by electrochemical technique. Physical properties of the
solution and duct side length were changed to provide Sc.Gr range of
7.38 x 10(8) - 1.4 x 10(11). Under these conditions the data were corr
elated by the equation Sh = 0.382(Sc.Gr)(0.278) A comparison between t
he measured overall rate of mass transfer with that calculated by summ
ing the rates of mass transfer at the separate sides of the duct showe
d that the measured value is higher than the calculated value owing to
convective interaction between adjacent surfaces.
