Abstract
The results of the experimental studies of local momentum transfer process in the region of the cylindrical wall of an agitated vessel equipped with an eccentric axial flow impeller are presented. The data for eccentrically located impellers both, propeller and HE 3 impeller, differing in the operating liquid pumping mode were compared. In total, 5120 experimental points for both impellers were obtained on the basis of the electrochemical experiments for each of the tested impeller. Axial and angular distributions of the shear rate and friction coefficient in the agitated vessel without baffles were found within the turbulent regime of the Newtonian liquid flow. Local shear stress, dynamic velocity and energy dissipated were also identified in this region of the wall. The results of the study show that the profiles of the transport coefficients depend strongly on the eccentricity e/R, axial and angular coordinates, liquid circulation imposed by axial flow impeller, and liquid turbulence in the agitated ve...
