Unsteady flow regimes of a nonrectilinear polymer jet under tension

The flow of a free jet of polymer solution or melt between a nozzle supplying fluid at a constant flow rate and a takeoff device in the form of a uniformly rotating roll is studied. The exit and takeoff points (the latter being the point at which the jet touches the roll surface) are on the same lev...

Zusammenfassung:The flow of a free jet of polymer solution or melt between a nozzle supplying fluid at a constant flow rate and a takeoff device in the form of a uniformly rotating roll is studied. The exit and takeoff points (the latter being the point at which the jet touches the roll surface) are on the same level, while the jet itself lies in a vertical plane. The jet sags under gravity by an amount that depends on the tension, the fluid density, the flow zone length, and the relationship between the takeoff and exit velocities.
