Viscosity of Newtonian and non-Newtonian Fluids

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.

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 ... 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.
