✦ Synopsis

A new apparent viscosity function for shear thickening fluids is proposed, contemplating the three characteristic regions typically exhibited by these materials: slight shear thinning at low shear rates, followed by a sharp viscosity increase over a threshold shear rate value (critical shear rate), and a subsequent pronounced shear thinning region at high shear rates. The proposed function has a continuous derivative, making it appropriate in numerical simulations. Moreover, the function is shown to provide an excellent fit to several independent experimental data sets.

## Abstract The anomaly of shear thickening at high shear rates can be observed under certain conditions for high molecular weight polymers dissolved in low‐viscosity Newtonian solvents despite the fact that shear‐thinning behavior is considered the norm for these fluids. The nature of the shear‐th
