Parameters influence on mixing time of gas liquid agitation system

Abstract EN

An experimental study for turbulent two-phase flows agitated by an impeller in a mixing tank is presented.

All the experiments carried out in a stirred tank with three types of impellers.

conductivity meter method has been used to evaluate the mixing time, effect of sodium chloride trace, impeller geometry, its speed and flow rate of gas phase on mixing time has been investigated.

Results show that the mixing time is dependent on the amount of tracer added to the system, and decreasing with increasing the impeller speed into single and two phase systems.

Also, is shown that different flow regimes can affect the final concentration of conductimeter.
