Unsteady gravity-driven rivulet flow of non-Newtonian power-law fluids with strong surface-tension effect / Nurul Ashikin Shaipudin

The study investigates the unsteady flow behaviour of rivulets formed by non-Newtonian power-law fluids under the influence of gravity wuth strong surface-tension effects. These rivulets exhibit distinct behaviours in response to different power-law exponents N that determine the shear-thinning or -thickening qualities. Their dynamics are characterised by the power-law fluid behaviour. The stream flow, on slanted surfaces and accelerated by gravity, is examined with the important impact of surface tension in mind.
