Residence time distribution is an important factor for the design of continuous-flow reactors. Quantitative statement can be given also for complex conditions by use of different models (diffusion-type, cellular-type, and channel-type model). The longitudinal dispersion coefficient is a criterion for the residence time behaviour. Besides a review of the published results obtained in cylindrical single-phase-flow reactors new experimental results are given for the longitudinal mixing of two-phase flow in up-flow columns.
