Turbulence is a complex and chaotic phenomenon that occurs in many fluid flows. It is characterized by irregular, three-dimensional motions that can lead to enhanced mixing, heat transfer, and energy dissipation. One of the most significant challenges in turbulence modeling is predicting the behavior of turbulent flows in complex geometries.
To solve non-Newtonian fluid problems, researchers often employ specialized constitutive models, such as the power-law model or the Carreau model. These models describe the rheological behavior of non-Newtonian fluids and can be used to predict their flow behavior in various geometries.
Non-Newtonian fluids exhibit complex rheological behavior, such as shear-thinning or shear-thickening, which cannot be described by the traditional Navier-Stokes equations.
