研究了低雷诺数下两种上随体麦克斯韦流体在管内共挤流动的线性稳定性。由于各种机制，流体界面可能变得不稳定。结果表明，流体的弹性可以稳定毛细不稳定性和线性稳定的界面，可以通过适当的选择控制参数。
The linear stability of co-extrusion flow of two upper convected Maxwell fluids through a pipe at low Reynolds numbers is studied for arbitrary wavelength disturbances. The fluids interface can become unstable due to various mechanisms. It is shown that elasticity of the fluids can stabilize the capillary instability and a linearly stable interface can be achieved by appropriate choice of controlling parameters.
