Experimental investigation of unsteady cooling behavior on a trailing edge cutback surface The vortex structure formed by the trailing edge cutback lip induces intense unsteady effects on the cutback surface, thereby significantly influencing the dist

Cooling is rarely steady. Experiments show how #HeatTransfer changes dynamically during rapid temperature drops. These transient effects matter for boiling regimes and could help refine models of #VaporLayer formation.

Fake or fact: Acetone can display the Leidenfrost effect.

FACT. Acetone has a low boiling point (~56 °C) and vaporizes quickly. On a surface significantly hotter than its boiling point, it can form a stable vapor layer, allowing the droplet to levitate and move around. So: FACT, acetone is indeed a good candidate for the Leidenfrost effect.

Dynamics of double-droplet centered impacting a hydrophobic surface featuring a micro-ridge Upon impact, the droplets undergo spreading and receding phases, with the total duration of these processes defined as the contact time. In this study, the latt

Simulations show two droplets hitting a micro‑structured hydrophobic surface bounce differently depending on spacing and angle. This dynamic is useful for surface engineering.

Can the Leidenfrost effect be switched off using an electric field? A droplet on a very hot surface can levitate on its own vapor cushion: the Leidenfrost effect, as spectacular as it is puzzling. But could we learn to control it? Could an electric field locally switc...

On #WomenInScience day, we welcome Lorena Victoria García to #LeidenForce.

Fake or fact? The Leidenfrost effect prevents the droplet from touching the surface, so it doesn’t heat up.

Answer: FALSE (partly). The vapor layer separating the droplet from the surface strongly limits direct heat transfer. This slows the heating down, but does not suppress it: heat is still transferred through the vapor layer and by internal fluid motion. As a result, the droplet eventually evaporates — much more slowly than with direct contact.
