非牛顿流体固粒悬浮流的若干问题

REVIEW OF SOME RESEARCHES ON SUSPENSION OF SOLID PARTICLE IN NON-NEWTONIAN FLUID

  • 摘要: 非牛顿流体固粒悬浮流具有广泛的应用背景,其特殊的流动属性使其成为一些新兴技术领域的核心突破点。同时,该流动又比较复杂,即便是在低固粒浓度的情况下,非牛顿流体特性也会对整个系统的微结构产生重要的影响,从而进一步影响固粒的运动。本文给出了非牛顿流体方程、固粒运动方程和非牛顿流体固粒悬浮流的特征参数,分析了这些参数的作用;阐述了单个固粒在管道中的径向移动、多固粒的相互作用和聚集、多固粒形成的链状结构以及非圆球固粒运动等方面的研究成果、结果分析以及尚未解决的问题,并对以上问题进行了总结和展望,给出了需要深入研究的具体问题和内容,旨在为进一步的研究提供参考和依据。

     

    Abstract: Suspension of solid particle in non-Newtonian fluid has a wide range of applications, and its special flow properties make it the core breakthrough point in some new technology fields. Meanwhile, the flow is more complex. Even in the case of low particle concentration, the characteristics of non-Newtonian fluid have an important influence on the microstructure of the whole system, which further affects the movement of solid particles. In this paper, the non-Newtonian fluid equation, particle motion equation and characteristic parameter of suspension of solid particle in non-Newtonian fluid are given, and the effect of these parameters is analyzed. The research findings, result analysis and open questions of some topics including the radial motion of single solid particle in a pipe, the interaction and aggregation of multi-particles, the chain structure formed by multi-particles, and motion of non-spherical particles are related. Finally, the topics mentioned above are summarized and prospected, and the concrete problems and contents that need to be studied deeply are given, which is aimed at providing references and basis for further research.
