Bingham plastic non-newtonian fluid
WebOct 11, 2024 · The Bingham plastic model for non-Newtonian fluids is another common viscosity model used in hydraulic analysis. This model states that the shear rate resulting from a given shear stress applied to the fluid can be described with Equation 3. WebNon-Newtonian Flows . R. Shankar Subramanian . Department of Chemical and Biomolecular Engineering . Clarkson University . Fluids such as water, air, ethanol, and benzene are Newtonian. This means that a plot of shear stress versus shear rate at a given temperature is a straight line with a constant slope that is independent of the shear rate.

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. WebJan 16, 2024 · Bingham plastic is a non-Newtonian fluid that behaves as a solid until a certain amount of pressure is applied, at which point it begins to behave as a liquid. Viscoelastic fluid is a fluid that has both viscous and elastic properties. It exhibits shear-thinning behavior, meaning that its viscosity decreases with increasing shear rate. ...
