"Breakthrough Model Predicts Flow of Blood and Unusual Fluids"

Researchers have developed a new model to predict the behavior of non-Newtonian fluids, such as blood and cornstarch mixtures, which exhibit unique properties like elastic turbulence. This advancement could have significant industrial applications, including optimizing the flow of slurries and biological solutions. The study, led by Marco Rosti at the Okinawa Institute of Science and Technology, reveals that elastic turbulence in non-Newtonian fluids shares similarities with classical turbulence in Newtonian fluids, offering new insights into fluid dynamics.

"Elastic Turbulence Shares Surprising Similarities with Newtonian Turbulence"

Researchers from OIST, TIFR, and NORDITA have discovered that elastic turbulence in non-Newtonian fluids shares more similarities with classical Newtonian turbulence than previously thought. Their study, published in Nature Communications, reveals that elastic turbulence exhibits a universal power-law decay of energy and intermittent behavior, challenging existing views and paving the way for a comprehensive mathematical theory to describe this phenomenon.

Unveiling the Secrets of Oobleck-like Fluids for Smart Material Design

Researchers at the University of Chicago's Pritzker School of Molecular Engineering have used piezoelectric nanoparticles to study the physics of non-Newtonian fluids, such as oobleck. They discovered that friction between particles plays a crucial role in the transition of these fluids from a liquid to a more solid structure. This understanding could lead to the design of new non-Newtonian fluids with practical applications, such as paint that doesn't clump, liquids that harden when shaken, and wearable protective gear that stiffens upon impact. The research also paves the way for the development of adaptive and responsive materials that become stiffer under mechanical force.
