Magnetic fields can dramatically reorganize fluid motion.
Using coupled fluid–thermal–structural simulations, this work shows how MHD effects suppress jets and vortices while altering heat transfer, mass transport and wall stresses.

#OnThisDay in 1826, physicist Georges Sire was born. His thesis on the “globular state of liquids” contributed to the early study of the #LeidenfrostEffect.

Long before high-speed imaging and numerical simulations, Georges Sire was already investigating the behavior of liquids on hot surfaces. On the anniversary of his birth, we look back at the work of this 19th-century physicist and his contribution to the early study of the Leidenfrost effect. Read more

Tiny pressure oscillations can strongly affect #BubbleDynamics during #boiling.
Understanding these instabilities is key to predicting transitions toward #Leidenfrost states and improving #HeatTransfer control in extreme thermal conditions.
Droplet impacts on superheated surfaces do not cool smoothly. This study shows a nonlinear shift driven by vapor film dynamics.
Above a critical impact velocity, heat transfer jumps sharply, revealing a threshold behavior linked to the Leidenfrost regime.

How do vapor bubbles behave when water is below boiling?
Laser-induced bubbles offer a controlled way to probe nucleation and collapse dynamics far from equilibrium.

Beyond a simple overview, this article traces the scientific history of the phenomenon, while providing a rich and detailed perspective on the dynamics of Leidenfrost droplets.
Enjoy the read!
