WebYasuki Nakayama, in Introduction to Fluid Mechanics (Second Edition), 2024. 2.5.2 Pseudoplastic Fluid. In contrast to a Bingham fluid, a pseudoplastic fluid is a fluid that increases viscosity as force is applied. A typical example is a suspension of cornstarch in water with a concentration of one to one. WebMay 29, 2024 · Bingham fluid. A material for which, in uni-directional shear flow, the shear stress $ \tau $ and the shear rate (velocity gradient) $ e $ satisfy the constitutive law. $$ \tag {a1 } \tau = \tau _ {0} + \eta _ {0} e ( \tau > \tau _ {0} ) , $$. when $ \tau \geq 0 $, with the obvious extension to $ \tau < 0 $. This can be written in terms of an ...

WebBingham-plastics Numerous examples of polymer flow models based on generalized Newtonian behaviour are found in non-Newtonian fluid mechanics literature. Using experimental evidence the time-independent generalized Newtonian fluids are divided into three groups. These are Bingham plastics, pseudoplastic fluids and dilatant fluids. … WebA fluid is shear thickening if the viscosity of the fluid increases as the shear rate increases (see Figure 2). A common example of shear thickening fluids is a mixture of cornstarch and water. You have probably seen examples …
WebJul 20, 2024 · A common example of a thickening or dilatant fluid substance is a corn-starch solution in water. Visco-Plastic Fluids. For this type of behavior, there is a minimum stress threshold, called ‘yield stress’, that must be exceeded for the fluid to flow or deform. ...

Web9.5.4 Dilatant Fluids. Dilatant fluids are also referred to as shear-thickening fluids. The viscosity of these fluids will grow with increasing shear rate. For these fluids, the exponent Eq. 9.4 is n > 1. Typical examples of dilatant fluids are thick suspensions of particles in a liquid.
