Free convection mass transfer rates at the outer surface of the inner duct of a horizontal square annular duct were measured by an electrochemical technique that involved measuring the limiting current of the cathodic deposition of copper from acidified copper sulphate solution. Physical properties of the solution and equivalent diameter of the annular duct were varied to provide Sc.Ga range of 1.1 × 1011-3.3 × 1012 which corresponds to 4.05 × 108 < Sc.Gr < 9.6 × 1010. Under these conditions the data were correlated by the equation: The insensitivity of the rate of mass transfer to the buoyancy force under the present conditions was accounted for by bulk flow (body force) dominance. A comparison between the measured mass transfer rate with that calculated by summing the rates of mass transfer at the separate sides of the inner duct showed that the measured value is higher than the calculated value. |
