Application of exact coherent structures to transition and turbulence. This project aims to understand coherent structures and devise methods to prevent bypass transition to turbulence and reduce turbulent wall drag. Coherent structures in turbulence may be identified with nonlinear solutions of the exact equations of motion. Such "exact" coherent structures have their Reynolds number dependence described explicitly and apply for moderate to very large Reynolds numbers, well above the range of f ....Application of exact coherent structures to transition and turbulence. This project aims to understand coherent structures and devise methods to prevent bypass transition to turbulence and reduce turbulent wall drag. Coherent structures in turbulence may be identified with nonlinear solutions of the exact equations of motion. Such "exact" coherent structures have their Reynolds number dependence described explicitly and apply for moderate to very large Reynolds numbers, well above the range of full Navier–Stokes calculations. Understanding the fundamentals of turbulence is expected to lead to more efficient and cheaper air transportation, and better tools for climate prediction and short-term weather forecasting.Read moreRead less
A Novel Approach To Flow Control By Topography. 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, ....A Novel Approach To Flow Control By Topography. 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.Read moreRead less
