Abstract The objective of this study was to investigate overall and structural parameters ofturbulence in a stirred tank Overall studies were carried out in a fully baffled vesselstirred by a Rushton turbine impeller Mean radial velocities impeller pumpingcapacity and mixing time were measured in this tank Effect of Reynolds number andimpeller off bottom clearance on pumping capacity and mixing time wereinvestigated Experimental results showed that pumping coefficient was independenton Reynolds number and off bottom clearance Mixing time decreased by increasingReynolds number and number of baffles but it increased by decreasing off bottomclearance Structural studies were done in a tank geometrically similar to PVCsuspension polymerization reactors of Bander Imam Petrochemical Company Thistank was equipped with a curved blade impeller Two short baffles were mounted onthe wall of the tank Instantaneous velocities were measured at different points of thetank and for different baffles angles Frequency of coherent structures decreased byincreasing distance from impeller and increasing baffles angle from 60 to 90 andto 120 so when baffles angle were 60 mixing increased in the tank
