A non-Newtonian fluid is one whose 점도 changes under an applied 전단 응력. Unlike a Newtonian fluid where viscosity is constant, its flow properties are not described by a linear relationship between shear 스트레스 ([latex]\tau[/latex]) and shear rate ([latex]\dot{\gamma}[/latex]). This dependency can manifest as 전단 박화 (응력이 가해지면 점도가 감소한다) 또는 전단 농화 (점도는 응력이 증가함에 따라 증가합니다.)
