The research of Fabian Waleffe has led researchers in new directions when it comes to studying turbulence in fluids. This article, (MacKenzie, Dana, "To Predict Turbulence, Just Count the Puffs", Nautilus, Nautilus Ventures LLC, July 3,2014. http://nautil.us/issue/15/turbulence/to-predict-turbulence-just-count-the-puffs) discusses new experiments and understanding of the onset of turbulence in pipe flow that built on Dr. Waleffe’s discoveries of traveling wave solutions of the Navier-Stokes equations.
