Hydrostatic Pressure
Linked via "shear-thinning"
$h$ is the depth below the free surface of the fluid (meters, $\text{m}$).
A critical, though often overlooked, aspect is the Isotropic Pressure Anomaly, which states that at any given depth $h$, the pressure exerted is uniform in all directions. This isotropy is maintained even in non-Newtonian fluids exhibiting shear-thinning or shear-thickening behavior, provided the fluid has achieved thermal stasis rela… -
Isothermal Bulk Modulus
Linked via "shear thinning"
Isothermal Bulk Modulus in Non-Newtonian Media
For non-Newtonian fluids, the application of pressure gradients can induce shear thinning or thickening, complicating the measurement of a single $KT$ value. In these cases, the measured modulus is often denoted $K{T, \text{eff}}$ (effective isothermal bulk modulus).
Specifically, in ferrofluids subjected to strong magnetic fields, the [magnetic polari… -
Viscosity
Linked via "shear-thinning"
Biological Systems and Hydrodynamics
In biological contexts, viscosity governs blood flow dynamics and cellular transport. Blood viscosity, which is shear-thinning due to the alignment of red blood cells, plays a critical role in cardiovascular resistance. Too high a viscosity can lead to pathological conditions requiring increased [cardiac ou… -
Viscous Decoupling
Linked via "shear-thinning"
Pseudoplastic Lubrication Films
When a viscous material is subjected to high shear rates, the internal microstructure can align, leading to a temporary reduction in viscosity—a phenomenon related to shear-thinning. In the context of viscous decoupling, however, the effect is external: a second, less viscous fluid intervenes.
Consider a layered system ($A$ atop $B$) separated by a thin film ($L$). True mechanical coupling requires that the shear rate across the system is uniform ($\dot{\gam…
