摘要
本文讨论了非牛顿流体的入口收敛流动问题,考虑到粘弹性流体在流动中的粘滑行为,应用最小能原理,导出了扩展的入口收敛流边界流线方程和流体自然收敛锥角方程,并与前人的工作进行了比较和分析。
In this paper, a converging flow of Non-newtonian fluids in an entrance has been discussed. Considering the stick-slip behavior of viscoelastic liquids in this ;,flow, an extended equation in converging flovy boundary streamline and an extended equation of natural converging conical angle in entry flow are derived, using a theory of minimal energy. And then, the results are compared with those given in literature.
