The project will resolve important questions concerning the influence of boundary topography on transition to turbulence and on the exact coherent structures forming the backbone of turbulence. The canonical topography known from previous work by one of the investigators is a wavy wall and, as well as resolving important issues in flow physics, the research is relevant to many flows of importance such roughness induced transition on aircraft wings, flows in heat transfer/mixing devices, blood flow and the influence of topography on the atmospheric boundary layer. Expected outcomes are an understanding of the interplay between transitional and turbulent flows with wall topography together with strategies to enhance mixing and drag reduction.

该项目将解决有关边界地形对向湍流过渡的影响以及形成湍流主干的确切相干结构的重要问题。 其中一位研究人员从以前的工作中了解到的典型地形是波浪壁，除了解决流动物理中的重要问题外，这项研究还与许多重要的流动有关，如飞机机翼上的粗糙度引起的转变、换热/混合装置中的流动、血液流动以及地形对大气边界层的影响。 预期的结果是了解过渡流动和湍流与壁面地形之间的相互作用，以及加强混合和减阻的战略。
