Mixing of a Viscoplastic Fluid in an In-Line Mixer

In this study, power consumption and design parameters of a newly designed in-line rotor stator-mixer were investigated particularly for inelastic non-Newtonian fluids. The power consumption of the mixer was measured experimentally using by viscoplastic fluids under the laminar flow case. Then obtained experimental data has been validated by means of numerical methods. It has been shown that experimentally and numerically deduced power-draw values are in a good agreement. Finally, numerically obtained velocity and shear rate profiles within the mixing heads were examined for the three rotational speed of the impellers.
