WebThe Bingham plastic model describes the flow characteristics of different kinds of mud and is described mathematically as: T - shear stress, γ - shear rate, YP - yield point and PV - plastic viscosity. Fluids that obey this model are called Bingham plastic fluids. PV should be low by minimizing colloidal solids to enable fast drilling while YP ... WebJan 17, 2015 · Toothpaste is what is called a non-newtonian fluid, more specifically toothpaste is a Bingham plastic. This means that the viscosity of the fluid is linearly dependent on the shear stress, but with an offset called the yield stress (see figure below). This yield stress is what makes it hard to say whether it is liquid or solid.
WebFeb 11, 2024 · Types of non-Newtonian fluids include dilatants, pseudoplastics, Bingham plastics, and Bingham pseudoplastics. Non-Newtonian fluids even include those whose viscosity depends on the shear rate history of the fluid, meaning the viscosity changes as the fluid is deformed at a constant rate. WebJan 7, 2024 · Bingham plastics exhibit a linear relationship between shear stress and rate of strain but, unlike Newtonian fluids, this relationship does not exhibit a zero intercept at zero strain rate. The intercept at zero strain rate is called the yield. Bingham plastic. Newtonian. Bingham plastic. Newtonian. Rate of strain in the fluid d Figure 5.1 …
