✦ Synopsis

Techniques have been developed for measuring the interfacial area in gas-liquid dispersions. It has thus been possible to measure the liquid-phase mass transfer coefficients in gas-liquid dispersions such as are produced in aerated mixing vessels, and sieve and sintered plate columns. The results have been combined with other published data for heat and mass transfer in liquid-liquid and solid-gas dispersions in which the dispersed phases are free to move under the action of gravity, and also with data on transfer by free convection from spheres. These data can all be correlated by

This length corresponds to a certain time taken by the fluid to adjust its velocity profile, and if in pulsed flow the period of the pulsations is much greater than the adjustment time, then the quasi-steady state assumption is valid. The condition for validity can be written: In the present work a
