Abstract Longitudinal mixing in reciprocating and pulsed sieve‐plate columns has been investigated for single‐phase flow and is described by a model in which both back‐mixing between stages and axial mixing within stages is considered. The model proposed expresses the effect of the amplitude, frequency, flow‐rates, distance between trays, their fractional free area and hole size on longitudinal mixing. The relations proposed have been verified by experiments, and the values of the constants in the correlation have been determined.
