The limiting current technique is used to obtain mass transfer coefficients at very low Reynolds numbers (Re less than 0.1) in a packed bed consisting of stainless steel spheres. The data show that for Re less than 0.015, the Nusselt numbers are below those predicted by existing empirical correlations. The results are discussed in the light of some mathematical models for packed beds reported in the literature and show semiquantitative agreement with the values predicted by Sorensen and Stewart (1974a).
