Dilatant shear thickening fluid
WebMar 1, 2012 · These are non-Newtonian fluids, and their viscosity increases with either increasing shear rate or applied stress [1]. STFs are ceramic-polymer composites, wherein a ceramic powder is dispersed... WebA shear thickening fluid (STF) is a material whose viscosity increases dramatically when the shear rate is above a critical value. It is an example of a non-Newtonian fluid and also termed a dilatant fluid. At low shear rates, the liquid has low viscosity and acts as a lubricant, and it flows easily; however, at higher shear rates, the

Shear Thickening Fluid: Theory and Applications provides a complete reference on shear thickening fluid (STF) and STF applications for engineers, researchers, and scientists. STF rheology is discussed in terms of several factors, including suspension medium, particle size, particle shape, and environmental conditions.
WebThe shear-thickening behavior of the polymers has a negative effect on the injectivity of the fluid. Since the flow rate is high near the injection and production wells, the injection pressure might become more than that of formation parting pressure. This leads to fracturing the reservoir rock. WebFeb 19, 2024 · Some non-Newtonian suspensions exhibit these properties such as toothpaste, paint, mayonnaise and shaving cream. Dilatant fluids exhibit shear thickening properties, i.e. the fluid viscosity increases …
