Highlights

?Linear stability of stratified flow of Newtonian/shear-thinning fluids is studied.

?The Carreau model has been chosen for the modeling of shear-thinning liquids.

?A working methodology is proposed to alleviate the search for the stability boundary.

?The obtained results highlight the limitations of the widely used power-law model.

?Case studies of gas–liquid and liquid–liquid systems are presented.

Abstract

Linear stability of horizontal and inclined stratified channel flows of Newtonian/non-Newtonian shear-thinning fluids is investigated with respect to all-wavelength perturbations. The Carreau model has been chosen for the modeling of the rheology of a shear-thinning fluid, owing to its capability to describe properly the constant visc
