WebBefore discussing non-Newtonian fluids, let’s first examine what is meant by a “New-tonian” fluid. In addition to his many other discoveries, Isaac Newton did some ground-breaking work with fluids. He discovered that the viscosity of most fluids is only affected by temperature. Viscosity is the quantity that describes a fluid’s ... 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. Webdeformation and flow.
