WebExamples of Bingham plastic fluids: toothpaste, mayonnaise, chocolate, mustard. These fluids need a force to be applied before they can flow. Their viscosity doesn’t change …
WebIt can be described mathematically as follows: τ = YP + PV (γ), where τ = shear stress γ = shear rate YP = yield point PV = plastic viscosity. Fluids obeying this model are called Bingham plastic fluids and exhibit a linear shear - stress, shear-rate behavior after an initial shear stress threshold has been reached. The viscosity of a shear thickening fluid, or dilatant fluid, appears to increase when the shear rate increases. Corn starch suspended in water ("oobleck", see below) is a common example: when stirred slowly it looks milky, when stirred vigorously it feels like a very viscous liquid. A familiar example of the opposite, a shear thinning fluid, or pseudoplastic flui…

WebTypical examples for pseudo-plastic fluids are polymer solutions and similar solutions of high molecular weight substances. At low shear rates, these liquids will experience the formation of shear stress. The shear stress results in the reordering of the molecules in order to reduce the overall stress. incorporating a fhlincl momsWebAug 28, 2024 · Bingham plastic fluids, which require some force threshold be surpassed to begin to flow and which thereafter flow proportionally to increasing shear stress.
