主 题：coherent structure turbulent flow heat transport geometrical confinement dynamical constraint
摘 要：Tuning transport properties through the manipulation of elementary structures has achieved great success in many areas,such as condensed matter physics.However,the ability to manipulate coherent structures in turbulent flows is much less explored.This article reviews a recently discovered mechanism of tuning turbulent heat transport via coherent structure manipulation.We first show how this me chanism can be realized by applying simple geometrical confinement to a classical thermally driven turbulence, which leads to the condensation of elementary coherent structures and significant heat-transport enhancement,despite the resultant slower flow.Some potential applications of this new paradigm in passive heat management are also discussed.We then explain how the heat transport behaviors in seemingly different turbulence systems can be understood by this unified framework of coherent structure manipulation.Several future directions in this research area are also outlined.
