Abstract
This work has the objective of modeling different non-Newtonian fluid laws from heterogeneous mixtures between water and minerals, showing as advantages and disadvantages found in the method employed of viscosity variation, to increase the transport efficiency of the same. The study method shows numerical methodologies of CFD, using the opensource software openfoam, together with the validation of experimental results obtained in the literature, as well as of fluid characterization methods, for the determination of the productions by this type of Material in transport piping. With the results produced by paths to studies of this type can be shortened, always seeking the most efficient method for each situation. Variable viscosity had results not to rely on further experimental data for value interpolation.
