Thesis title
Predicting viscous and pressure drag over multi-scale rough surfaces in wall bounded turbulence.
Research overview
Surface roughness and drag prediction is becoming a popular field in fluid mechanics research, as it strongly influences fuel consumption, emissions, and operating costs for a wide range of engineering applications, including ships, aircraft, and wind engineering. The wide range of unavoidable surface roughness in these applications (such as coating roughness, weld seams, repair marks, and environmental fouling) makes drag prediction challenging. In particular, the transitionally rough regime remains veiled in uncertainty, as do cases with very sparse and low slope surfaces, and cases with heterogeneity. This study builds on recent developments in physical modelling and aims to develop a drag prediction approach that more reliably captures mutual sheltering, heterogeneous roughness, and viscous and pressure stress partitioning.
