Viscous Beads Flowing Down a Vertical Fibre

This lecture explores the dynamics of a fluid flowing down a vertical fibre, leading to the formation of droplets driven by gravity. Different flow regimes are observed depending on system parameters, such as fibre radius and liquid flow rate. An evolution equation for the interface is derived to capture the flow characteristics. The study includes experimental setups, theoretical formulations, and numerical simulations to understand the complex interfacial dynamics.
