COLLAPSIBLE TUBE FILLING
- Collapsible Tube Filling is a phenomenon that occurs in stesdy flow in tubes with significant distensibility.
- Such conditions occur rarely in industrial applications but are very common in biological studies.
- Understanding the physical origin and nature of these phenomena remains a significant experimental, analytical, and computational challenge, involving unsteady flows at low or high reynolds numbers, large-amplitude fluid-structure interactions, free-surface flows, and intrinsically 2D or 3D motion.
- Whereas frequently the internal flow involves a single fluid phase in many instances.
- The presence of two or more distinct flowing phases is of primary importance.
