Abstract: | Momentum transfer was investigated in an unbaffled agitated vessel of inner diameter 0.3 m equipped with different off-centred
impellers. The distribution of the shear rate on the tank wall as a function of the impeller type and Reynolds number was
studied in the turbulent regime of the Newtonian liquid flow. The dependences of the averaged dimensionless shear rate, friction
coefficient, and dissipated energy on the Reynolds number and eccentricity ratio were approximated using four-parameter equations.
