WebFeb 19, 2024 · A Newtonian fluid is one that keeps a constant value of viscosity across all shear rates. They get this moniker because they follow the formula set out by Isaac Newton in his law of fluid mechanics. Fluids that don’t exhibit constant viscosity across all shear rates are known as non-Newtonian fluids. WebFor all Newtonian fluids in laminar flow the shear stress is proportional to the strain rate in the fluid where the viscosity is the constant of proportionality. However for Non Newtonian fluids, this is no longer the case as for these fluids the viscosity is not constant.
