摘要
A model is derived for a viscoelastic fluid jet based on a one-dimensional directed curve idealization. It incorporates the general influences on the free surface geometry of surface tension, inertia viscosity, elasticity and gravity. The model is applied to the case of an axisymmetric torsionless jet and the fluid jet phenomena of extrudate swell and draw-down under gravity are described. Some planned future applications of the model are indicated.
