Researchers believe Leonardo da Vinci’s 500-year-old “paradox” has finally been solved.
There are many things in the world Science It has baffled scientists for decades.
One such mystery is Leonardo da Vinci’s Bubble Paradox.
this paradox It refers to the way air bubbles spiral or zigzag on their way to the water surface instead of going straight up.
For years, scientists have tried to explain why this happens, but to no avail — that is, to this day.
A new explanation was proposed by Prof. Miguel Ángel Errada of the University of Seville and Prof. Jens G. Eggers of the University of Bristol.
For details of the survey results, new research published Published in the Proceedings of the National Academy of Sciences.
In this study, researchers perform simulations that reproduce high-precision measurements of the phenomenon.
This is known as using “numerical discretization techniques”. InterestingEngineering.com.
What scientists have discovered is that once a bubble reaches a certain radius, it is pushed into a new unstable path.
This occurs due to the interaction of water flow and the subtle collapse of its shape.
of researcher The study added, “The movement of bubbles in water plays a central role in a wide range of natural phenomena, from the chemical industry to the environment.
“Single-bubble buoyancy ascent works as a much-studied paradigm, both experimentally and theoretically,” they continued.
“Despite these efforts, and despite the enormous computational power immediately available, it is difficult to reconcile experimental and numerical simulations of the complete hydrodynamic equations of deformable bubbles in water. I could not do it.
“This is especially true of the interesting observation already made by Leonardo da Vinci, that large enough bubbles exhibit periodic motion rather than rising along a straight line.”
The researchers believe that the results of this study could aid in the future understanding of particles.
