WebMay 1, 2024 · Non-Newtonian fluid flow in porous and fractured media is of considerable technical and environmental interest. Here, the flow of a non-Newtonian fluid in a variable aperture fracture is studied theoretically, experimentally and numerically. We consider a shear-thinning power-law fluid with flow behavior index n. The natural logarithm of the … WebPower law model is applicable for time independent non-Newtonian fluids and can be written as. τ = K γn. where, τ is shear stress, γ is shear rate, K is called flow consistency index and n is called flow behavior index. For n < 1, the apparent viscosity decreases with increasing shear rate and fluid is called pseudoplastic or shear-thinning. WebThe viscosity of water at 20 °C is 1.0020 millipascal seconds (which is conveniently close to one by coincidence alone). ...
