ABSTRACT In this work, we have conducted computer simulations of laminar mixing generated within a retreated-blade paddle and a flat-blade paddle in a vessel tank. The three-dimensional flow of fluid is numerically analysed using the equations of continuity and motion. The computational method used is based on a finite volume discretization. The good agreement between the numerical results and the experimental data confirm the validity of the analysis method.
