Low shear

WebIn general, one can say that high laminar shear stress is atheroprotective, while low shear stress or oscillatory shear stress tends to enhance atherogenicity [2]. In fact, persistent high laminar shear stress reduces neointimal cell proliferation [ 12 , 13 ] and may also determine regression of an already installed neointimal layer [ 14 ] (see Atherosclerosis … Web23 dec. 2024 · These viscoelastic fluids possess some solid-like qualities (elasticity), particularly at low shear rates, along with the usual liquid-like qualities (viscosity). Shear-thinning drilling fluids, such as xanthan gum-based fluids, tend to be viscoelastic and can lower efficiency of low-shear-rate devices like static separation tanks and centrifuges.
