Mass transfer to the wall of a packed and unpacked bubble column operating with Newtonian and non-Newtonian liquids

Mass transfer to the wall of a bubble column is examined, focusing on the influence of the liquid viscosity. The effect of introducing structured packing in the column is analysed by comparing results for the empty column with those of packed column at similar operating conditions. Visual observatio...
