先前对细长粘弹性和牛顿自由表面射流的研究主要集中在稳态预测，主要以工业纺织品应用为指导。纤维流动的动力学分析和模拟，甚至是非平凡稳态的线性稳定性分析，都落后于大量的实验和纺织加工观察和进展。 Chang 和 Lodge [Rheol. Acta.，10 (1971)，第 448–449 页] 和 Petrie [Rheol。 Acta., 14 (1975), pp. 955–957]，[Elongational Flows, Pitman, London, 1979] 已通过 Beris 和 Liu 的轴对称建模和模拟进行了扩展 [J.非牛顿流体力学，26 (1988)，第 363–394 页]，[计算。方法应用机甲。 Engrg., 76 (1989), pp. 179–204]，对于麦克斯韦流体，以及 Markovich 和 Renardy [J. Non-Newtonian Fluid Mech., 17 (1985), pp. 13–22] 用于 Johnson–Segalman 流体。 [Markovich 和 Renardy] 中的模型是一个单一的非线性抛物线方程，其中弹性延迟提供了主导的平滑...
Previous studies of slender viscoelastic and Newtonian free surface jets have focused mainly on steady state predictions, guided primarily by industrial textile applications. Dynamical analyses and simulations of fiber flows, even the linearized stability analysis of nontrivial steady states, have lagged behind considerable experimental and textile processing observations and advances. The foundational work of Chang and Lodge [Rheol. Acta., 10 (1971), pp. 448–449] and Petrie [Rheol. Acta., 14 (1975), pp. 955–957], [Elongational Flows, Pitman, London, 1979] has been extended by the axisymmetric modeling and simulation of Beris and Liu [J. Non-Newtonian Fluid Mech., 26 (1988), pp. 363–394], [Comput. Methods Appl. Mech. Engrg., 76 (1989), pp. 179–204], for Maxwell fluids, and Markovich and Renardy [J. Non-Newtonian Fluid Mech., 17 (1985), pp. 13–22] for Johnson–Segalman fluids. The model in [Markovich and Renardy] is a single, nonlinear parabolic equation in which elastic retardation provides dominant smooth...
