- A generalized Newtonian fluid is an idealized fluid for which the shear stress is a function of shear rate at the particular time, but not dependent upon the history of deformation. Although this type of fluid is non-Newtonian (i.e. non-linear) in nature, its constitutive equation is a generalised form of the Newtonian fluid. Generalised Newtonian fluids satisfy the following rheological equation: where is the shear stress, and the shear rate. The quantity represents an apparent or effective viscosity as a function of the shear rate. The most commonly used types of generalized Newtonian fluids are:
* Power-law fluid
* Cross fluid
* Carreau fluid
* Bingham fluid It has been shown that Lubrication theory may be applied to all Generalized Newtonian fluids in both two and three dimensions. (en)
- 廣義牛頓流體（英語：generalized Newtonian fluid）是一種理想流體，其剪應力為特定時間點之剪切速率的函數，與變形過程無關。儘管此類型流體屬於非牛頓流體（即非線性流體），但其本構方程與牛頓流體一致。廣義牛頓流體滿足以下流變方程： 其中，為剪應力，而為剪切速率。為表觀或有效黏度，為剪切速率的函數。 常用的廣義牛頓流體模型有：
* 冪律流體
* 克羅斯流體
* 卡羅流體
