Turbulent Flow Over Surfaces With Spatially Varying Roughness

Abstract

This project aims to improve understanding of the effect of spatial roughness transitions on turbulent flows. Fluids flowing over non-smooth surfaces influence our daily lives, such as water moving through a pipe, wind blowing over the Earth's surface or aircraft moving through air. The presence of surface roughness profoundly influences these flows. Though engineers have learnt to deal effectively with evenly distributed roughness, this is seldom encountered in reality. Rather, there are abrupt changes in roughness, for example at the edges of wind-farms or at rivets on aircraft. This project aims to investigate these important, but little understood, turbulent flows. Potential benefits inc..
