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. WebFluid shear stress is the tangential component of frictional forces generated at a surface (e.g., the vessel wall) by the flow of a viscous fluid (e.g., blood), and affects the physiology of the cells 1.Conventional static cell culture does not allow reproducing such phenomenon while microfluidic is rising as an efficient tool for studying cell behavior under perfusion 2.
