Text of Abstract
Using a novel high-speed photography technique we visualize the interaction between two colliding viscoelastic jets. At different regimes of flow rate, geometrical configurations and liquid viscoelasticity we observe a variety of interesting morphologies. Finally, we focus on a certain regime of parameters for which the formed fluid structure resembles a fishbone. Because of the control on the size distribution of the generated droplets, this phenomenon can have applications in micro-droplet generation or emulsification processes.
