The mixing time is the function of the diameter, number, location of plugs and the tracer injection situation. It was shown that the variation of mixing time is not obvious with the increasing of plug diameter, the stirring efficiency is better if plug number is increased and plugs are distributed in deep and off-central region in vessel, since the angular velocities occur and the more stirring power is obtained in these layouts.
