【摘要】 静电纺丝是生产纳米纤维最方便、最直接和最经济的方法之一,其力学机理的研究作为解决静电纺纳米纤维瓶颈问题的关键一直受到各相关领域的关注。本文采用数值方法研究静电纺丝过程中两相射流的力学机理,建立多场(电场、磁场、振动力场和流场)耦合作用下的静电纺丝两相流模型,并在此基础上对射流流场进行数值模拟,所得数值结果与实验结果吻合良好,表明该方法可准确预测此射流流动。更多还原

【Abstract】 Electrospinning has been recognized as one of the most convenient,a direct and economical method for the fabrication of polymer nanofibers,and its mechanical mechanism has been received much attention in recent years.In this paper,numerical simulations have been carried out to research mechanical mechanism of the electrospinning process.A two-phase model for electrospinning process under coupled field forces is established.And a computational fluid dynamics technique is applied to simulate the two-phase flow for gaining significant insight into understanding of its mechanical mechanism.The calculation results are reasonable and reliable.It is concluded that the CFD method is a powerful approach to research mechanical mechanism of the electrospinning process and it is very important for the development of electrospinning.更多还原
