Circulation and mixing times in turbulent agitated tanks

3 Circulation and mixing times in turbulent agitated tanks [Pg.705]

Circulation times are measures of the average bulk fluid motion generated by the liquid pumping of the impeller in a stirred tank. Measurements of circulation and mixing times help us to understand the scalar transport in the tank. [Pg.705]

Circulation times are associated with the tank s total volumetric flow rate, entrainment flow, and the pumping capacity of the impeller. [Pg.705]

The mean circulation time, 9c, is given by the total tank volume divided by the pumping capacity [87, 64] [Pg.705]

The mean circulation time represents an average value for all the fluid elements in the tank and provide information on how fast the fluid parcels are transported around in the tank. [Pg.706]
