Slip length estimation and flow reconstruction from micro-particle image velocimetry via functional uniqueness guarantees Slip length, a fundamental measure of solid–fluid interaction, plays a crucial role in the inversion and reconstruction of flow-field parameters. However, near-

How do fluids really slip on surfaces? This study proposes a method to estimate #SlipLength and reconstruct flow fields from limited data. A key step to better understand flows where friction at the wall nearly vanishes.

Dynamics and universal scaling of Worthington jets in the cavity-free regime Existing research on Worthington jets has paid most attention to those forced by cavity collapse. Focusing on the cavity-free regime across various sphere-liquid impact configurations, we derive a uni...

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

Effects of surface wettability on bubble dynamics and induced liquid flow: Finite-difference analysis of two-phase particle image velocimetry Bubble dynamics is critical for mass, momentum, and heat transport in two-phase flows. We investigated the effects of surface wettability on bubble formation, departure, and the surrounding liquid flo...

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