Researchers verify 70-year-old theory of turbulence in fluids

uq.edu.au
  • After 70 years, physicists have confirmed a theory which states that adding energy to a two-dimensional system will eventually cause giant vortices to appear.
  • Understanding this phenomenon can bring immense cost and environmental benefits to many industry and transport processes.
  • The study involved stirring a superfluid with precisely focussed laser beams, creating vortex structures one tenth the size of a human blood cell.
  • Turbulence physics causes enormous inefficiencies, and these findings might lead to greener, more efficient machines across many industries.
