Darwin microfluidics shear stress
WebFluid flow commences once the applied shear stress exceeds the critical yield stress. This flow commonly follows shear thinning behavior. Some fluids, however, possess a yield stress followed by Newtonian flow. These types of fluids are referred to as Bingham fluids. WebDec 3, 2024 · Our microfluidic device consisted of five portions divided by arrays of micropillars. The generated shear stress gradient has five distinct levels at 8.38, 6.55, …
