Many modern drilling fluid systems are non-Newtonian. The shear-thickening properties allow for more effective cuttings transport and more effective hole cleaning. read more
The shear-thickening properties allow for more effective cuttings transport and more effective hole cleaning. Both traditional, clay viscosified and newer polymer viscosified systems exhibit non-Newtonian behavior with this behavior having to "engineered" into the polymer-based systems; it is the default behavior in clay-based systems. read more
The shear modulus is one of several quantities for measuring the stiffness of materials. Source: Shear Modulus on Wikipedia. which is another fancy work to say that a fluid does not oppose resistance to any shear force, as it is not rigid. read more
Viscosity of Newtonian and non-Newtonian Fluids. If you are on this site, you probably have a general idea about what is viscosity and how important it is in the development of any application that involves fluid flow. However, fluid characterization is far more deep and complex than what is usually expected. read more
