Mass transfer in packed beds at low Reynolds numbers

Mass transfer coefficients for packed beds of Raschig rings were measured by the electrochemical technique in the low Reynolds number range, where both, free and forced convection are important. From the analysis of the governing basic equations the parameters controlling the combined free and force...
