We tried in this study to numerically analyze the mixing process for high concentration slurry liquids having a plastic rheological property, and in which unevenness of both, viscosity and concentration, disappear with agitation, from an initial situation in which the viscosities are different in the upper and lower halves of a stirred vessel. We verified the reliability of the analyzed results by comparing them with measurements of mixing time and the power consumption required to attain mixing. The numerical analysis enabled us to understand the correlation equations of the mixing process for a heterogeneously viscous system in which the initial viscosity varies through the vessel and to estimate the mixing performance from a local point of view in the vessel.
