Thesis title
Investigating Important Roughness Parameters on Aerodynamic Drag using Numerical Simulations
Research overview
The surface roughness on airplanes and the hull of ships due to paint blistering, rivets, corrosion and even living biological fouling dramatically increase drag and hence increase fuel consumption and greenhouse gases emissions. Therefore, a fundamental understanding of turbulent rough-wall boundary layers and the topographical surface features that contribute to drag would have a two-fold effect in reducing operational costs and emissions. High-fidelity numerical simulations, which contain three-dimensional, time-resolved information of the flow will be used to generate a database of the turbulent flow over roughness. With the produced database, novel machine-learning techniques will be utilised to unravel the near-wall physics of the flow.
