宾汉流体

对于宾汉流体，针对经典宾汉流体模型带来的佯谬，本文采用双粘度模型成功解决了这一问题，开拓了屈服应力流体蠕动流的研究工作。

A paradox will be encountered in the problem of Bingham peristaltic flow if classical Bingham plastic fluid model is adopted ; hence a bi-viscosity model for Bingham fluid is employed to solve the problem and the study in the thesis improves the investigations of peristaltic flow of yield-stress fluid .

n，且n值小于1，凝胶的起始运动存在一个屈服应力τy，说明这种凝胶是一种假塑性宾汉流体。
