  "term": "Power-law fluid",
  "field": "Oil and gas",
  "definition": "A non-Newtonian fluid model used to describe the rheological behavior of drilling fluids, where the shear stress is proportional to the shear rate raised to a power. This model characterizes fluids that exhibit shear-thinning or shear-thickening properties, unlike Newtonian fluids with constant viscosity. The power-law model is defined by two parameters: the flow behavior index (n) and the consistency index (K).",
