Abstract
Aim. We consider the rheological behavior of a nanofluid obtained on the basis of titanium oxide nanoparticles in water and ethylene glycol.
Methodology. The experimental data are approximated using equations of the structural rheological model on separate intervals of the shear rate.
Results. A relationship is obtained between the coefficients of rheological equations and the nature of changes in the structure of the nanofluid, namely, the formation and destruction of nanoparticle aggregates.
Research implications. Equations are derived that make it possible to approximate experimental data at individual shear rate intervals corresponding to a certain structural state of the nanofluid.
