Waves dictate the yo-yoing decay of a viscoelastic mixing layer

Communications Physics - Many fluids encountered in nature and industry, such as polymer solutions, are elastic and behave very differently from water. We show that elasticity causes the mixing...

Invariant rate of energy extraction by polymers in turbulence

Polymeric flows exhibit phenomena that sit at odds with our conventional understanding of turbulence. In this work, we show how a characteristic far-from-Kolmogorov self-similarity of polymeric...

“If the three-body problem is complex, imagine the 100,000-body problem.” Unprecedented simulation of sediment-filled fluids mixing uncovers new behaviors and enables new studies of supernovae, chemical refining, and beyond. @CFF_OIST @PhysRevLett oist.jp/news-center/news/202…

How fast does smoke rise, rain fall, and a supernova explode?

Fluid simulation at an unprecedented scale provides a new scientific toolkit for fundamental physics and applied fluid engineering.
