WebJun 9, 2024 · The two main flow properties of a cement slurry are shear rate and shear stress. These properties permit the determination of two slurry properties: Flow Behavior Index, n’, and (2) Consistency Index, K’. These factors will then allow estimation of the pumping rate for turbulence of slurry in the annuals, frictional pressure drop of slurry ... There are a number of other models that better describe the entire flow behaviour of shear-dependent fluids, but they do so at the expense of simplicity, so the power law is still used to describe fluid behaviour, permit mathematical predictions, and correlate experimental data. See more In continuum mechanics, a power-law fluid, or the Ostwald–de Waele relationship, is a type of generalized Newtonian fluid (time-independent non-Newtonian fluid) for which the shear stress, τ, is given by See more Dilatant, or shear-thickening fluids increase in apparent viscosity at higher shear rates. They are in … See more Just like a Newtonian fluid in a circular pipe gives a quadratic velocity profile (see Hagen–Poiseuille equation), a power-law fluid will result in a power-law velocity profile, where u(r) is the … See more Pseudoplastic, or shear-thinning are those fluids whose behaviour is time independent and which have a lower apparent viscosity at higher shear rates, and are usually See more A Newtonian fluid is a power-law fluid with a behaviour index of 1, where the shear stress is directly proportional to the shear rate: See more • Power law • Rheology • Navier–Stokes equations See more
