摘要：

The assumption of constant axial dispersion coefficient in residence time distribution (RTD) experiments is examined for liquid fluidized beds. Experimental results show this assumption to be violated in short beds. A quantitative criterion is proposed for the constraint required to achieve the true value of the axial dispersion coefficient in RTD experiments.
