| Abstract: | Abstract Based on the locus of ink on the well-rotating disc, a model for the mean residence time of liquid in a rotating packed bed, t = ?′ ε (ctg(α2/2) ? ctg (α1/2))ωu), is proposed. Model predictions agreed with the reported data with relative error within ±15%. A modified surface renewal model based on Danckwerts,  | |
