Designer Turbulence

Abstract

Turbulence is inevitable in the transportation arena: go fast enough under realistic operationalconditions and flow cannot remain i"n the streamlined, laminar state. This transition comes withenormous cost in terms of fuel spent, noise, and emissions, in aviation"", shipping, pipelinetransportation and individual transportation. Further, turbulent mixing processes dominate largescaleenvironme""ntal flows. Despite this ubiquity and the fundamental nature of turbulence (andover a hundred years of related research), the dynam""ics of turbulence are still poorly understood.Attempts to control turbulent flows close to walls remain empirical, costly and ineff"icient ~ andessentially impractical as a consequence. A successful modeling approach that is tied to thegoverning equations of mot"ion, the Navier-Stokes equations, has been lacking.
