挤压流在楔形模拟了许多实际过程，如润滑，涂层和液体食品的感官评价。本文采用幂律流体模型，给出了楔体中有滑（或润滑）和无滑挤压流动的解析近似解。解决方案似乎并不比两个平行圆盘之间的挤压流更复杂，并且可以用作入口粘度和食物扩散的心理-物理模型的变体。另一种方法是，可以根据本文所述的方程式研制一种液体食品流变仪。
Squeezing flow in a wedge simulates a number of practical processes, e.g. lubrication, coating and the sensory evaluation of liquid foods. This paper reports analytical approximate solutions for both slip (or lubricated) and no-slip squeezing flow of liquid food in a wedge, in which the power law fluid model was used. The solutions do not seem to be more complex than that for squeezing flow between two parallel disks and may be used as a variation of the psycho-physical models of in-mouth viscosity and food spreadability. Alternatively, a rheometer for testing liquid foods may be developed according to the equations described in this paper.
