Thesis Title
The Effects of Spatial and Temporal Heterogeneity of a Rough Wall on Wall-Bounded Turbulence
Research overview
The chief source of drag in applications such as ships, airplanes and wind-turbines is skin-friction drag due to turbulent flows. Surface roughness on the walls of these applications, which is often unavoidable, increases the drag further causing inefficiencies. The current uncertainty in drag prediction is estimated to cost up to $60 billion annually. While many models for drag prediction have been proposed, they generally assume the roughness to be homogeneous, isotropic and rigid. Practical roughness tends to be patchy (anisotropic, spatially heterogeneous) and dynamic (temporally heterogeneous). My work investigates turbulent flows over these types of heterogeneous roughness through wind-tunnel experiments.
