How do fluids really slip on surfaces?

This study proposes a method to estimate slip length and reconstruct flow fields from limited data.

A key step to better understand flows where friction at the wall nearly vanishes.

When a drop or object hits water, a narrow high-speed jet can shoot upward: the Worthington jet. This study reveals universal scaling laws that govern how these jets form and evolve across different impact conditions.

A key takeaway for LeidenForce: surface wettability radically reshapes the surface–bubble–flow coupling—smaller bubbles, higher detachment frequency, stronger vortical flows.
