You Didn’t See It Coming: the Spontaneous Nature of Turbulence
UC San Diego Professor of Physics Nigel Goldenfeld has shown in theoretical models of turbulence that even molecular motions can create large-scale patterns of randomness over a defined period of time.
Prototype telescope designed by Lawrence Livermore researchers launched to the International Space Station
A prototype telescope designed and built by Lawrence Livermore National Laboratory (LLNL) researchers has been launched from Cape Canaveral, Florida to the International Space Station (ISS).
Building an understanding of quantum turbulence from the ground up
Researchers show how energy disappears in quantum turbulence. The discovery paves way for a better understanding of turbulence in scales ranging from the microscopic to the planetary
Physicists Uncover New Dynamical Framework for Turbulence
Physicists at Georgia Tech have proven — numerically and experimentally — that turbulence in fluid flows can be understood and quantified with the help of a small set of special solutions that can be precomputed for a particular geometry, once and for all.
Physicist Greg Hammett honored for his work advancing understanding of fusion plasmas
Theoretical and computational physicist Greg Hammett, a leader in advancing understanding of the complex turbulence that controls the performance of fusion plasmas and a dedicated educator, has been named a 2021 Distinguished Scientist Fellow by the DOE’s Office of Science.
Squid Jet Propulsion Can Enhance Design of Underwater Robots, Vehicles
Squids use a form of jet propulsion that is not well understood, especially when it comes to their hydrodynamics under turbulent flow conditions. Discovering their secrets can help create new designs for bioinspired underwater robots, so researchers are exploring the fundamental mechanism. They describe their numerical study in Physics of Fluids; among their discoveries, they found that thrust production and efficiency are underestimated within laminar, or nonturbulent, flows.
This Supernova in a Lab Mimics the Cosmic Blast’s Splendid Aftermath
(Study publishes 6/17/20. No embargo.) Mystery enshrouds the birth of swirls typical for supernova remnants like the Crab Nebula. A new “supernova machine” may help solve it.
A New Parallel Strategy for Tackling Turbulence on Summit
A team at Georgia Tech created a new turbulence algorithm optimized for the Summit supercomputer. It reached a performance of less than 15 seconds of wall-clock time per time step for more than 6 trillion grid points—a new world record surpassing the prior state of the art in the field for the size of the problem.
